Ideas, Experiments, and Lessons Learned
I spent three months building what I thought was a masterpiece. Clean architecture. Proper separation of concerns. Full test coverage. Everything I learned in my career, poured into this side project. Then I stopped working on it. Not because I got busy. Not because I lost interest. I stopped because it was too damn hard…
Four hours. I wasted four hours chasing a bug that turned out to be a single missing character. Here’s what happened and why I’ll never make this mistake again. The Scenario I was working on a Node.js API that handled user authentication. Everything worked fine locally. But in production, certain login requests would just hang….
The Most Embarrassing Bug I Ever Shipped Four hours. I spent four hours staring at logs, checking git diffs, rolling back deployments, and questioning my entire career — all because of a typo. What Happened We had a payment webhook that was supposed to update user subscriptions. Everything worked fine in staging. But in production,…
Let me be honest — I used to think error handling was boring. Just wrap things in try-catch and move on, right? Wrong. That mindset cost us hours of debugging at 2 AM. After dealing with enough production fires, I started collecting patterns that actually work. These aren’t theoretical best practices — they’re the things…

My microservices origin story I used to roll my eyes every time someone mentioned microservices. “Just use a monolith,” I’d say. “You’re overcomplicating things.” And for years, I was right. Most startups don’t need microservices. They need working features. But then my side project grew. What started as a simple REST API became something bigger….
For years, I wrapped everything in try-catch blocks. Every function, every API call, every database query. I thought that’s what defensive programming looked like. I was wrong. The Problem with Catching Everything When you catch exceptions at every level, you lose context. You mask real errors. You make debugging a nightmare because you never know…

I’ll be honest — I used to think context switching wasn’t a big deal. “Just switch tasks,” I’d tell myself. How hard can it be? Then I looked at my calendar and realized I’d jumped between 7 different projects in a single day. And accomplished basically nothing. What Context Switching Actually Costs Here’s the thing…
Three hours. That’s how long I stared at my screen, questioning my career choices, doubting everything I knew about programming. And the culprit? A single character typo. The Setup I was building a simple API endpoint. Should’ve taken 20 minutes. But something wasn’t working. The response kept returning null instead of the expected data. I…
