A LITTLE MORE ABOUT THE PERSON

I design, build,
and ship.

Full-stack engineer and designer with 4+ years of turning ideas into production-ready products.

I’m Mir Sadat Bin Rakib, a full-stack engineer and designer who enjoys transforming ambitious ideas into intuitive, scalable, and visually engaging products.

Over the past four years, I’ve worked across software engineering, AI systems, frontend development, and UI/UX design. I’ve contributed to startups, launched products reaching thousands of users, and built independent projects from concept to production.

My approach combines engineering discipline with design thinking. I believe great products should be technically reliable, visually distinctive, and genuinely useful.

Outside of engineering, I explore design systems, creative coding, AI tools, content creation, and building products of my own.

A FEW THINGS I BELIEVE

Good products start
with good intentions.

01

People before pixels.

A beautiful screen means very little if people can’t find what they need. Understanding comes before styling.

02

Reliable by design.

Great products should be technically sound. The systems underneath matter as much as the surface people see.

03

Distinctive and useful.

Visually memorable and genuinely helpful belong together. The best work is easy to use and hard to forget.
