Years Old

Who I
Am.

I'm Sabbir Hassan, a full-stack developer and designer based in Dhaka, Bangladesh. I work at the intersection of engineering and aesthetics — writing systems-level code in Rust, shipping cross-platform apps in Flutter, and crafting interfaces in Figma and Adobe XD that people actually enjoy using.

Beyond building for clients, I sharpen my problem-solving through competitive programming in C++ on LeetCode, and I document everything I learn through technical writing on MkDocs.

Experience

6+ Years

Every pixel is intentional — design and code go hand in hand.

Performance matters. Fast, clean, maintainable code is non-negotiable.

I build products I'd be proud to use myself.

Documentation is part of the work, not an afterthought.
