Résumé

About

I'm Abrar Mahir Esam, a software engineer based in Dhaka. I like understanding how things work, and making them work a little better.

The short version

At Bengal Byte I was one of the first engineers on Psycloud, a production clinical platform now serving over 1,000 users, and a principal architect of the product. I also architected a government personnel and duty-management platform running 300 concurrent users.

I work end to end across Spring Boot (Java 21), FastAPI and Node.js behind React and Next.js, over PostgreSQL, MongoDB and Redis, and I publish open-source developer tooling in Rust.

I'm a Codeforces Specialist (peak rating 1425, 496 problems solved) and have mentored three batches of competitive programmers at the MIST Computer Club. I earned my B.Sc. in CSE from MIST with a CGPA of 3.56/4.00, and I'm now pursuing my M.Sc. part-time.

Outside software, I write poems and draw, from quick sketches to Inktober.
