About Me
The engineer behind the work
I'm a full-stack software engineer based in Dhaka, Bangladesh, focused on building production-grade SaaS platforms, backend systems, and AI-powered automation.
My engineering philosophy is simple: ship software that's reliable first, fast second, and delightful third. I care about clean architecture, meaningful tests, and systems the next engineer can reason about quickly.
I'm motivated by solving real operational problems — the kind that save teams hours every week rather than just looking good in a demo. Lately that's meant a lot of work at the intersection of backend engineering and applied AI.
Long-term, I want to keep growing as a systems-level engineer: owning architecture end to end, mentoring other engineers, and eventually building products of my own.
