about.md

I’m a backend-focused engineer based in Rajshahi, Bangladesh, shipping production systems for globally distributed teams. My work centres on FastAPI, NestJS, Go, and Rust microservices — with a strong bias toward clean API contracts, event-driven architectures, and observability from day one.

I enjoy the quiet parts of the job: taming database hotspots, keeping deploys boring, writing tests that catch the things humans miss, and turning vague business requirements into reliable services. I collaborate well with product, design, and ops — and I mentor junior engineers through code review and pairing.

Currently building an enterprise contract-lifecycle platform at Cognitus, an IBM Company. Previously led back-end at Grype Digital and delivered full-stack work for clients including the Bangladesh Navy.
