Software Engineer building dependable backends and full-stack products. Based in Dhaka, Bangladesh.
CSE graduate with a major in Software Engineering, working across .NET and the TypeScript ecosystem. I care about correctness under load, clean architecture, and systems that fail gracefully. Alongside product work I compete in programming contests and do research when it matches with my interest.
