Hi, I'm Mahir

Hasin Mahir
{ }</>◆

Web, Mobile, Embedded. One Engineer.

Full-stack products across firmware, apps, and the web — no handoffs, no gaps.

I take ideas from bare hardware to shipped product — writing embedded firmware, building mobile apps, and shipping the cloud and web layers that tie it together.

About

About me

I’m a software engineer with a passion for building thoughtful, well-crafted products. I care about performance, accessibility, and the little details that make software feel great.

When I’m not shipping code, you’ll find me exploring new tools, or writing about what I learn.
