01 — About

Engineer at heart, designer by discipline.

I care about the details that don't ship in changelogs — the 20ms you save, the state machine you didn't need, the empty state you actually designed.

Portrait of MD Sabbir Hossain

Building software with clarity, speed, and taste.

I'm a first-year CSE undergraduate. My work sits at the intersection of high-quality user interfaces and systems that stay boring under load. Outside of coursework, I ship side projects, contribute to open source, and grind competitive programming.
