Software Engineer
About
Engineer by trade, competitor by instinct.
I build systems in Java/Spring Boot and C#/.NET, along with the Angular frontends running on top of them, around one principle: failure is not a release note, it's a design flaw.
Over 3.5 years that's meant validation pipelines that catch bad data before it lands, notification delivery that survives server crashes without losing a message, and account-security layers that close real attack surfaces — plus a hotel-integration platform automating booking, cancellation, and payment workflows across 21 hotels and 20 booking sources, with 10+ integrations delivered personally. The stack changes — Node.js, Express.js, React.js, Python/FastAPI — the standard doesn't.
Competitive programmer by training — 1st out of 10,715 participants in CodeChef's March Long One (Division 4), an ACM ICPC Regionalist, and 14th in Pakistan on Google Kick Start — which means constraints are design inputs and worst-case behaviour gets thought about before it becomes someone else's incident report.
Currently
Going deep on system design, distributed systems, and data structures & algorithms — because the gap between code that works and code that's production-ready is where the real engineering happens.

Competitive Programming
Ranked where it counts.
Competitive programming isn't decoration. It shapes how constraints become design inputs and how worst-case behaviour gets considered before it becomes someone else's incident report. The certifications below apply that same rigor to the fundamentals.
