CLAUDE.md for Redis: 13 Rules That Stop AI From Writing Cache Anti-Patterns

You ask Claude to "add caching to the user profile endpoint," and 30 seconds later you ship something that looks fine in review: SET user_42 <json> — flat key, no namespace, collides the moment a second service shares the cluster. No TTL — the entry lives forever until maxmemory evicts your hottest keys. KEYS user_* in a cleanup job — single-threaded Redis stalls every other client for h...

Behind the Scenes of AWS Student Community Day Amravati

When people attend an event, they see the stage, the speakers, the sessions, and the energy. Everything looks smooth, organized, and perfectly timed. But what they don’t see is the chaos, pressure, and countless small decisions happening behind the scenes. AWS Student Community Day Amravati was exactly that kind of experience. On the surface, it looked like a well-executed tech event with 550+ st...

Why I Chose Regex Over AST Parsing in My SAST Tool (And When That Would Be Wrong)

In my last article, I mentioned that my SAST tool uses regex-based pattern matching instead of AST parsing, and that this was a deliberate tradeoff. A few people asked me to go deeper on that decision — because on the surface, it sounds like I took a shortcut. I didn't. Or rather — I did, but it was an informed shortcut, and there's a meaningful difference. Let me explain what AST parsing actual...

Why Most Crypto Bots Get Sandwiched (And How to Prevent It) If you've ever run a trading bot on Ethereum or Solana, you've probably experienced the frustration of watching your profitable trade get "sandwiched" - where some MEV bot frontruns your transaction and backruns it, stealing most of your profit. In this post, I'll explain exactly how these sandwich attacks work, why most bots a...

Who cares about speed?

After 8 years of software engineering, the one thing I am good at is something that nobody really cares about. This reality has hit me hard many times. Who cares about performance if it costs you slightly more investment. Who cares about architecture if it costs you more. Who cares about 0.35 second of improvement or even 2 seconds of faster load time for that matter. This was a very strange real...

Immutable List in Java

Engineering Craftsmanship: Building a Sovereign Immutable List in Java In an era of "vibe coding" and AI-driven bloat, there is a distinct value in returning to the fundamentals of structural integrity. As I navigate a career pivot toward Site Reliability Engineering (SRE) and Senior Development, I’ve found that the most resilient systems are those built on the principles of data sovere...

10 Reasons Why Web3 Projects Fail After Launch

Web3 is no longer an early market — it’s a competitive environment. And the uncomfortable truth is that most projects don’t fail because of bad timing or market conditions. They fail after launch, when the hype disappears and real usage becomes the only metric that matters. Launching used to be the hard part. Today, it’s the easiest one. Working with Web3 products, I’ve repeatedly seen the same pa...

Stop Letting Your LLM Bill Spiral: Building a Multi-Tenant Gateway in Spring Boot

A team I worked with shipped their first LLM feature in two weeks. Six weeks later, they got a $47,000 OpenAI bill — for a free tier product. The post-mortem found three things: one tenant ran a script that retried failed requests indefinitely, another had a buggy prompt that asked the model to "respond in ten thousand tokens," and a third was just abusive — they had discovered the API key was ef...

Coding is Dead? No, it’s just getting started for 10-year-olds.

It started on a random Sunday afternoon at our kitchen table. I was playing around with an M5Stack Core2, "vibe-coding" a simple pixel face that made a sound when you tapped the screen. I thought it was a fun little experiment—until I showed it to my 10-year-old son, Justus. He looked at it, then at me, and said: "Dad, you can't leave it like that. It needs a life. It needs to eat, it needs to sl...

API Documentation is a Failed Concept. Here's What's Next.

Let's start with a controversial opinion: API documentation, as we know it, has failed. Think about it. Docs are: Static: They can't adapt to your specific question or use case. A Burden to Maintain: Which is why they're almost always outdated. One-Size-Fits-All: They treat a senior architect and a beginner the same way. We spend hours translating a static document into dynamic code. It's an ine...

How to catch AI hallucinations before they reach production

LLMs hallucinate. That's not news. What's underdiscussed is how that failure mode behaves in long working sessions: confident reconstruction that looks fluent, cites specifics, and feels right — until three sessions later when something supposed to be true turns out not to be. This is week 5 of an 8-week deep dive on CRAFT for Cowork, a structured working environment for Claude. The QA framework ...

Moving Data from MySQL to BigQuery (Without Turning It Into a Side Project)

You don’t notice the problem right away. Everything runs smoothly in MySQL… until a new report shows up. Then queries slow down, dashboards lag, and you start realizing you’re stretching the database beyond what it’s good at. That’s usually when BigQuery enters the picture. So the real question becomes: How do you actually move data between them without turning it into a side project? Le...
