About

I'm a software engineer based in Dhaka with over five years building enterprise-grade applications in .NET Core, .NET Framework, React, and Azure. Most of my work has been on one of the largest web-based healthcare SaaS platforms in the U.S., where I design microservices, lead a small team, and help keep mission-critical systems running.

I care about clean architecture, pragmatic performance work, and code that's easy for the next person to maintain. Outside of work I spent years in competitive programming — as a contestant, problem setter, and judge — which is where a lot of my problem-solving instincts come from.
