Productivity in 2025 is no longer about doing more tasks — it’s about doing the right things, faster, with AI as your multiplier.
As a senior frontend developer, you’re juggling:
AI helps you streamline all of this — if you use it right.
This article walks through how to be insanely productive, with real-world scenarios from a frontend engineer’s daily workflow.
Productivity = Time × AI Leverage × Focus — Distractions
AI gives you leverage.
Focus gives you momentum.
Together, they turn you into a 10× engineer without burning out.
As a senior dev, you shouldn’t spend time on:
AI can do all of that instantly.
You're building a “Saved Cards” screen. After finishing the UI:
Instead of writing this manually:
You paste your diff or code into AI and say:
“Generate a clear PR description, test cases, and UX edge cases for this component.”
You save 20–30 minutes per PR.
Multiply that over a year… that’s days of time saved.
As a senior dev, your biggest responsibility is decision-making.
Should you:
Instead of endless Google rabbit holes, AI helps you reason instantly.
You’re building a dashboard with frequent API updates.
Ask AI:
“Given a real-time dashboard with 10+ API calls, compare polling, WebSockets, and SSE with pros/cons, scalability, cost, and ease of implementation.”
You get:
AI becomes your architecture assistant, helping you avoid bad decisions.
Senior developers write more than juniors:
AI eliminates the blank-screen problem.
Your PM asks:
“Can you send a quick summary of the new caching strategy?”
Instead of typing manually, you say:
“Summarize this caching strategy in a non-technical tone for product managers.”
AI produces a clean paragraph. You edit it for accuracy. Done in 2 minutes.
Learning on the job is constant, especially in frontend where tools evolve daily.
You're debugging why a modal animation feels janky on low-end Android devices.
Ask AI:
“Explain how browser layout, paint, and composite cycles work using this example animation code.”
AI breaks down:
transform performs better than top/left
You learn in 5 minutes what could have taken an hour.
Side projects differentiate senior developers from others.
AI helps you build 3–5× faster.
You want to build a “Latency Checker for AWS Media Regions” (like you did).
You ask AI:
It doesn't replace you.
It boosts your throughput.
What used to take 2 weeks can now be done in 3 days.
Motivation dies.
Consistency wins.
AI helps you plan realistically.
On Monday, you tell AI:
“Help me plan my week as a senior frontend dev working on a dashboard project. Break tasks into 45-minute work blocks.”
It generates:
By Wednesday evening, you ask:
“Show me what I accomplished and what I should move to tomorrow.”
AI acts like:
You stay on track, even on low-motivation days.
After finishing code, ask AI:
“Review this code for readability, best practices, and performance. Suggest improvements.”
AI points out:
You're not just writing faster —
you’re writing better.
This compounds your skills over months.
AI writes code.
But only you know:
AI should assist —
not replace judgment.
AI writes a React Query hook.
You must still:
This is why senior devs remain invaluable.
The modern frontend ecosystem moves ridiculously fast:
The developer who learns faster
wins faster.
AI gives you:
All in one.
That's unfair leverage —
use it.
AI won't replace frontend developers.
But AI-augmented developers will outperform everyone else.
If you want to deliver more, grow faster, and stay ahead:
Don’t try to compete with AI.
Collaborate with it — and multiply your output.

Inspired by BulletProof React, I applied its codebase architecture concepts to the Umami codebase.
What is Umami?
What is a project structure?
Umami is an open-source, privacy-focused web analytics tool that serves as an alternative to Google Analytics. It provides essential insights into website traffic, user behavior, and performance, all while prioritizing data privacy.
Unlike many traditional analytics platforms, Umami does not collect or store personal data, avoiding the need for cookies, and is GDPR and PECR compliant.
Designed to be lightweight and easy to set up, Umami can be self-hosted, giving users full control over their data.
A detailed getting started guide can be found at umami.is/docs.
To get Umami up and running you will need to:
I pulled the above information from the Umami docs.
In Bulletproof React, Project structure documentation explains about the purpose of files and folders in src folder and talks about the feature folder.
When you work in a team, it is crucial to establish and follow standards and best practices in your project, otherwise every developer has their own preferences and in the end, you will end up with a spaghetti codebase.
Umami is built using Next.js. We will review the following folders in Umami codebase:
src
app
component
lib
permission
queries
store
tracker
To manage a project, you need to put files and folders where they belong so later on, you will know where to look for. Put things where they belong.
You cannot place database queries inside a components folder as this components can only hold UI components unless your team has a different meaning to a component and then may be you can place the queries inside a components folder.
For example, Umami’s components folder actually holds hooks and other things, so it is not just the UI components but rather components in their “system”.
Hey, my name is Ramu Narasinga. I study codebase architecture in large open-source projects.

In Jira administration, snapshots and sandboxes are often confused. Both are useful — but they solve very different problems:
Snapshots: Recover after something breaks.
Sandboxes: Prevent issues before they reach production.
Many teams rely on snapshots thinking they’re “safe testing.” In reality, snapshots only help after an issue occurs. Sandboxes let you test safely before users are affected.
🔄 Snapshots: Quick Fixes
Snapshots are great for rolling back misconfigurations or failed updates, but they have limits:
A rollback may stop the symptoms, but it won’t explain what caused the problem or prevent it from returning.
🧱 Sandboxes: Prevent Problems
A sandbox is an isolated, production-like Jira environment used exclusively for testing. It allows you to:
With sandboxes, you can experiment freely, test risky changes, and ensure production stays stable.
🧠 Snapshots vs Sandboxes
Snapshots:
Sandboxes:
Prevention is cheaper, faster, and less stressful than recovery.
🚀 Sandboxes Made Easy
Setting up sandboxes used to be slow: installing Jira, configuring clusters, restoring backups, matching production.
Today, automation tools can spin up production-like sandboxes in minutes, making safe testing a daily habit instead of a rare luxury.
🏁 Final Thought
Snapshots undo damage — sandboxes prevent it.
If you want to:
✔ Avoid plugin outages
✔ Test Jira upgrades confidently
✔ Debug issues without user impact
✔ Reduce downtime
✔ Build a stable, predictable Jira environment
Then sandboxes aren’t optional — they’re essential.
Snapshots fix symptoms 📸💥; Sandboxes prevent problems 🏖️✅
💬 Have you tried sandboxes in your Jira setup? What’s worked for your team?

Fortran, a powerful language widely used in scientific and engineering applications, continues to be relevant in 2025 due to its performance and efficiency in numerical computations. In this guide, you will learn how to write functions in Fortran, a fundamental concept that is critical for extending the language's capabilities. This article will also provide useful links to related Fortran resources for further learning.
Functions in Fortran are similar to subroutines, serving as reusable blocks of code. They are used to perform a calculation or process that returns a single value. Functions can encapsulate specific tasks, making your code more organized and easier to debug.
Here's a step-by-step guide on how to write a simple function in Fortran:
A function in Fortran is defined using the FUNCTION keyword. It must specify the type of value it returns. For instance, if you are writing a function to add two integers, the function’s return type will be INTEGER.
FUNCTION AddTwoNumbers(a, b) RESULT(sum)
INTEGER :: a, b
INTEGER :: sum
sum = a + b
END FUNCTION AddTwoNumbers
To use the function, you need to declare it in your main program or module. This enables the compiler to recognize and utilize the function within your Fortran code.
PROGRAM Main
INTEGER :: result
result = AddTwoNumbers(5, 10)
PRINT *, "The sum is ", result
END PROGRAM Main
Compile your Fortran code using a Fortran compiler like gfortran or ifort. Ensure your development environment is set up correctly to avoid build errors.
gfortran -o add_numbers add_numbers.f90
./add_numbers
As of 2025, integrating Fortran functions in mixed-language projects is increasingly common. You may face challenges when working alongside languages like C++. Using tools such as CMake can streamline the build configuration. For further details, check the Fortran and C++ build configuration resource.

Quick reference for acronyms used in this article:
Let's be real: most engineers interact with Large Language Models (LLMs) through a thin wrapper that hides what's actually happening. You send a string, you get a string back. It feels like magic.
But here's the thing—if you're building production LLM systems, especially as a data engineer responsible for pipelines that process millions of requests, you need to understand what's under the hood.
As a data engineer, you already know how to build pipelines, optimize queries, and manage infrastructure at scale. Now it's time to apply that same rigor to Artificial Intelligence (AI) systems—and understand the fundamentals that separate expensive experiments from Return on Investment (ROI)-positive production systems.
This isn't about reading research papers or implementing transformers from scratch. It's about understanding the three fundamental controls that determine:
Miss these fundamentals, and you'll either blow your budget, ship unreliable systems, or both.
Let me show you why these three concepts matter, starting from first principles.
💡 Data Engineer's ROI Lens
Throughout this article, we'll view every concept through three questions:
These aren't just theoretical concepts—they're the levers that determine whether your AI initiative delivers value or burns budget.
Here's what most people think: "A token is a word."
Wrong.
A token is a subword unit created through a process called Byte-Pair Encoding (BPE). It's the fundamental unit that Large Language Models (LLMs) process—not characters, not words, but something in between.
Think about it from a data engineering perspective. If we treated every unique word as a token, we'd have problems:
Problem 1: Vocabulary Explosion
Problem 2: Out-of-Vocabulary Words
[UNK]. Information lost.The BPE Solution:
BPE builds a vocabulary by iteratively merging the most frequent character pairs.
Here's the intuition:
['h', 'e', 'l', 'l', 'o']
'l' + 'l' → merge into 'll'
'he' + 'llo' → 'hello' (if frequent enough)Real Example:
Let's tokenize these strings (using GPT tokenizer):
"Hello World" → ["Hello", " World"] = 2 tokens
"Hello, World!" → ["Hello", ",", " World", "!"] = 4 tokens
"HelloWorld" → ["Hello", "World"] = 2 tokens
"hello world" → ["hello", " world"] = 2 tokens
Notice:
If you've worked with traditional Natural Language Processing (NLP) (think Term Frequency-Inverse Document Frequency (TF-IDF), bag-of-words), you know about stop words—common words like "the", "is", "at", "which" that are often filtered out because they carry little semantic meaning.
Here's the interesting part: LLMs don't use stop word lists. They tokenize everything.
Why?
Traditional NLP (Natural Language Processing) reasoning:
"The cat sat on the mat" → Remove stop words → "cat sat mat" → Easier processing, less noise
LLM (Large Language Model) reasoning:
"The cat sat on the mat" has grammatical structure. Those "meaningless" words actually encode relationships, tense, and context that matter for understanding.
Example:
That "is" vs "was" changes everything. Stop words matter.
But here's the tokenization insight:
Common words like "the", "is", "and" are so frequent that BPE assigns them single tokens. Rare words get split into multiple tokens.
"The" → 1 token (very common)
"Constantinople" → 4-5 tokens (less common)
"Antidisestablishmentarianism" → 8-10 tokens (rare)
So while LLMs don't filter stop words, they handle them efficiently through tokenization. Common words = cheap (1 token). Rare words = expensive (multiple tokens).
Data Engineering Implication:
When estimating token costs for text processing pipelines, documents with lots of common English words will be cheaper per character than documents with:
A 1,000-word customer support ticket in plain English might be 1,300 tokens. A 1,000-word legal document with Latin phrases and case names might be 1,800+ tokens.
Here's where it gets expensive for data engineers building global systems:
English: "Hello" → 1 token
Japanese: "こんにちは" → 3-4 tokens (depending on tokenizer)
Arabic: "مرحبا" → 3-5 tokens
Code: `def hello_world():` → 5-7 tokens
Why?
Most LLM tokenizers (like OpenAI's) are trained primarily on English text. Non-Latin scripts get broken into smaller byte-level tokens, inflating token count.
Cost Impact for Data Engineers:
If you're processing customer support tickets in 10 languages:
At $0.002 per 1K tokens (input) and $0.006 per 1K tokens (output):
Scaling to 1M tickets/month: That's $8K vs $20K—a $12K/month difference just from tokenization.
Real-World ROI Example:
A fintech company processing multilingual loan applications learned this the hard way:
Before understanding tokenization:
Reality check (production launch):
Ouch. 2.4x over budget.
After optimization:
Annual impact: $44K → $15K = $29K saved (66% cost reduction)
This is why understanding tokens, temperature, and context windows isn't academic—it's the difference between a profitable AI system and an expensive mistake.
Common mistake: Estimating tokens by word count.
Rule of thumb: 1 token ≈ 4 characters in English
But this breaks for:
- Code (lots of special characters)
- Non-English languages
- Text with heavy punctuation
- Structured data (JavaScript Object Notation (JSON), Extensible Markup Language (XML))
Example with JSON:
{"name": "John", "age": 30}
You might think: "That's like 6 words, so ~6 tokens."
Actual token count: 11 tokens
["{", "name", "\":", " \"", "John", "\",", " \"", "age", "\":", " ", "30", "}"]
Every brace, colon, quote—they often become separate tokens.
Lesson for Data Engineers: When building LLM pipelines that output structured data, account for the token overhead of formatting. A 100-word natural language response might be 125 tokens, but the same information as JSON could be 180+ tokens.
Modern LLMs use vocabularies of 50K-100K tokens.
GPT (Generative Pre-trained Transformer)-3/4: ~50K tokens
LLaMA (Large Language Model Meta AI): ~32K tokens
PaLM (Pathways Language Model): ~256K tokens
Why not bigger?
The final layer of an LLM computes probabilities over the entire vocabulary. With 50K tokens and a hidden dimension of 12,288 (GPT-4), that's a matrix of:
50,000 × 12,288 = 614,400,000 parameters
Just for the final projection layer. Larger vocabularies = more parameters = more compute.
Why not smaller?
Smaller vocabularies mean longer token sequences for the same text. Remember, attention mechanisms scale at O(n²) with sequence length. More tokens = more computation.
There's a sweet spot, and most modern LLMs landed on 50K-100K.
Here's what's actually happening when an LLM generates text:
Step 1: The model processes your input and produces logits (raw scores) for every token in its vocabulary.
logits = {
"the": 4.2,
"a": 3.8,
"an": 2.1,
"hello": 1.5,
...
"zebra": -3.2
}
These aren't probabilities yet—they're unbounded scores.
Step 2: Apply softmax to convert logits into a probability distribution:
P(token) = e^(logit) / Σ(e^(logit_i))
This gives us:
probabilities = {
"the": 0.45,
"a": 0.38,
"an": 0.10,
"hello": 0.05,
...
"zebra": 0.0001
}
Now we have a valid probability distribution (sums to 1.0).
Step 3: Sample from this distribution to pick the next token.
Temperature is applied before the softmax:
P(token) = e^(logit/T) / Σ(e^(logit_i/T))
Where T is temperature.
Temperature = 1.0 (default):
Temperature = 0.0 (deterministic):
Temperature > 1.0 (e.g., 1.5):
Temperature < 1.0 (e.g., 0.3):
Let's say we have these logits for the next token:
Original logits:
"the": 4.0
"a": 3.0
"an": 2.0
"hello": 0.5
At Temperature = 1.0:
After softmax:
"the": 0.53 (53% chance)
"a": 0.20 (20% chance)
"an": 0.07 (7% chance)
"hello": 0.016 (1.6% chance)
At Temperature = 0.5 (sharper):
Divide logits by 0.5 (= multiply by 2):
"the": 8.0
"a": 6.0
"an": 4.0
"hello": 1.0
After softmax:
"the": 0.84 (84% chance) ← Much more confident
"a": 0.11 (11% chance)
"an": 0.04 (4% chance)
"hello": 0.007 (0.7% chance)
At Temperature = 2.0 (flatter):
Divide logits by 2.0:
"the": 2.0
"a": 1.5
"an": 1.0
"hello": 0.25
After softmax:
"the": 0.36 (36% chance) ← Less confident
"a": 0.22 (22% chance)
"an": 0.13 (13% chance)
"hello": 0.06 (6% chance)
Key Insight: Temperature doesn't change the order of probabilities—"the" is always most likely. It changes how much more likely the top choice is compared to others.
Temperature = 0.0: Deterministic Tasks
Temperature = 0.3-0.5: Focused but Varied
Temperature = 0.7-0.9: Balanced Creativity
Temperature = 1.0+: High Creativity
Real-World Temperature ROI:
A legal tech company building a contract analysis tool discovered the hard way that temperature matters:
Initial approach (temp=0.7):
After understanding temperature (temp=0.0):
ROI Impact:
One parameter change. Massive return on investment (ROI).
Temperature alone isn't enough. Even at temp=0.7, you might sample a very low-probability token (the "zebra" with 0.01% chance).
Top-k Sampling:
Only consider the top k most likely tokens. Set the rest to probability 0, then renormalize.
Top-k = 3 means only consider the 3 most likely tokens:
"the": 0.53 → renormalized to 0.66
"a": 0.20 → renormalized to 0.25
"an": 0.07 → renormalized to 0.09
"hello": 0.016 → ignored (probability = 0)
Top-p (Nucleus) Sampling:
More adaptive. Instead of fixed k, include the smallest set of tokens whose cumulative probability exceeds p.
Top-p = 0.9 means include tokens until cumulative probability ≥ 90%:
"the": 0.53 (cumulative: 53%)
"a": 0.20 (cumulative: 73%)
"an": 0.07 (cumulative: 80%)
"hello": 0.016 (cumulative: 81.6%)
... keep adding until cumulative ≥ 90%
Why Top-p > Top-k:
Top-k is rigid. If the model is very confident, maybe only 2 tokens are reasonable, but you're forcing it to consider 50. If it's uncertain, maybe 100 tokens are plausible, but you're limiting to 50.
Top-p adapts to the model's confidence. High confidence? Small nucleus. Low confidence? Larger nucleus.
Most production systems use: temperature=0.7, top_p=0.9, top_k=0 (disabled)
You'd think temp=0 always gives the same output for the same input.
Not quite.
Even at temp=0:
For true determinism: Set temperature=0, top_p=1.0, seed=42 (and pray the API supports seeded generation).
The context window is the maximum number of tokens an LLM can process in a single request (input + output combined).
Common context windows:
But here's what data engineers need to understand: It's not just about "how much text fits." It's about computational complexity.
Transformers use self-attention, which computes relationships between every token and every other token.
For a sequence of length n, that's:
n × n = n² comparisons
Example:
Quadratic scaling is brutal.
This is why longer context windows are:
It's not an arbitrary limit. It's a memory and compute constraint.
During training, transformers are trained on sequences of a fixed maximum length (e.g., 8,192 tokens). The model learns positional encodings for positions 0 to 8,191.
What happens at position 8,192?
The model has never seen it. Positional encodings break down. Attention patterns become unreliable.
Modern techniques (like ALiBi, rotary embeddings) help extend beyond training length, but there are still practical limits.
Critical for data engineers: Context window includes input + output.
Context window: 8,192 tokens
Your prompt: 7,000 tokens
Model's max output: 1,192 tokens
If the model tries to generate more than 1,192 tokens, it'll hit the limit mid-generation and truncate.
Even worse: Some APIs reserve tokens for special markers, formatting, system messages. Your effective context might be 8,192 - 500 = 7,692 tokens.
Strategy 1: Sliding Windows
Instead of keeping full conversation history, maintain a sliding window:
Window size: 2,000 tokens
New message: 300 tokens
Option A: Drop oldest messages until total ≤ 2,000
Option B: Keep first message (system context) + last N messages
Option C: Keep first + last, drop middle (risky—loses context)
Strategy 2: Summarization
Periodically summarize old messages:
Messages 1-10: "User asked about product features. We discussed pricing, integrations, and support."
Messages 11-15: [keep full text]
Trade-off: Summarization costs tokens (you need to generate the summary), but saves tokens long-term.
Strategy 3: Retrieval-Augmented Generation (RAG)
Don't put everything in context. Store information externally (vector Database (DB)), retrieve relevant chunks, inject into context.
User query: "What's our refund policy?"
→ Retrieve top 3 relevant docs (500 tokens)
→ Include only those in context
→ Generate response
This pattern allows you to work with unlimited knowledge bases while staying within context window constraints.
If you're processing millions of documents, context windows create batch size constraints.
Example: Embedding Generation
You want to embed 100,000 customer support tickets (avg 500 tokens each).
Naive approach:
for ticket in tickets:
embedding = embed(ticket) # 1 Application Programming Interface (API) call per ticket
Result: 100,000 API calls. Slow. Rate-limited. Expensive.
Batch approach:
batch_size = 16 # Fit within context window
for batch in chunks(tickets, batch_size):
embeddings = embed(batch) # 1 API call for 16 tickets
Result: 6,250 API calls. Much better.
But there's a catch: If your context window is 8K tokens, and you batch 16 tickets at 500 tokens each = 8,000 tokens, you're at the limit. If one ticket is 600 tokens, you overflow.
Solution: Dynamic batching based on token count, not fixed batch size.
# Pseudocode
current_batch = []
current_tokens = 0
max_batch_tokens = 7500 # Leave buffer
for ticket in tickets:
ticket_tokens = count_tokens(ticket)
if current_tokens + ticket_tokens > max_batch_tokens:
# Process current batch
embeddings = embed(current_batch)
# Start new batch
current_batch = [ticket]
current_tokens = ticket_tokens
else:
current_batch.append(ticket)
current_tokens += ticket_tokens
This is basic data engineering—but it matters for LLM pipelines.
Context windows directly impact cost.
OpenAI Pricing (GPT-4):
Scenario: Customer support chatbot
Average conversation:
- System message: 200 tokens
- Conversation history: 1,500 tokens
- User message: 100 tokens
- Response: 200 tokens
Input tokens per message: 200 + 1,500 + 100 = 1,800
Output tokens per message: 200
Cost per message: (1.8 × $0.03) + (0.2 × $0.06) = $0.054 + $0.012 = $0.066
At 100,000 messages/month: $6,600/month
Optimization: Sliding window (keep last 500 tokens of history)
Input tokens per message: 200 + 500 + 100 = 800
Cost per message: (0.8 × $0.03) + (0.2 × $0.06) = $0.024 + $0.012 = $0.036
At 100,000 messages/month: $3,600/month
Savings: $3,000/month just from context management.
Understanding tokens, temperature, and context windows isn't academic—it's the foundation of every cost optimization, quality improvement, and scaling decision you'll make in production.
As a data engineer, you know that small inefficiencies compound at scale. A 20% optimization in query performance isn't just "nice to have"—it's millions of dollars when you're processing petabytes. The same principle applies to Large Language Model (LLM) systems.
