Welcome to my portfolio

Abul Hasnat - Hi, I’m Abul Hasnat

|

I lead teams that turn big ideas into software people actually want to use — not just tolerate.
With years of experience in building everything from snappy frontends to rock-solid backends, I make products that are fast, intuitive, and secretly complex under the hood.
My goal? To ship software that works so well, you’ll forget how much work went into it… and that’s exactly how it should be.
