The questions I ask before writing any code
The most expensive code I've written wasn't buggy. It worked perfectly — for a problem nobody actually had.

// About
Tech Lead with 7+ years building full-stack systems across MERN, Angular/Ionic, and microservices. I deliver Web, Android, and iOS from a single codebase and lead teams through code review, CI/CD automation, and AI-assisted workflows that measurably shorten delivery cycles.
I work best on complex full-stack products where clean architecture, performance, and delivery speed matter — translating business goals into scalable architecture, end to end.

All articlesHow I estimate a task I've never done before
Most bad estimates aren't bad math. They're a confident guess about the part of the task nobody has looked at yet.
Practices
How I decide what actually needs a test
Most test-coverage debates are about the wrong number. The question isn't "what percentage is tested" — it's "what breaks silently if this changes."
Testing
How I debug a bug I can't reproduce
Most bugs labeled "can't reproduce" aren't random. Something is different — the environment, the data, or the timing — and the bug is actually 100% reproducible once that difference is found.
