Building backend systems
that scale & think.

Full-Stack Developer / Backend Engineer / AI & ML Enthusiast

I'm Mustafizur Rahman — I design and build backend architecture, APIs, and intelligent systems, and I connect them to interfaces people actually enjoy using. Currently exploring distributed AI systems and scalable infrastructure.

FIG. 01 — ABOUT

The person behind the codebase

My programming journey started the way most good ones do — by breaking things and getting curious about why. What began as HTML and CSS experiments during my Computer Science degree turned into a genuine pull toward backend systems: the part of the stack most people never see, but that everything else depends on.

These days I spend most of my time designing APIs, modelling data, and figuring out how systems should talk to each other — then wiring a frontend on top that makes all of that invisible to the user. My thesis work on federated learning pulled me further into AI/ML, and I'm still chasing that intersection of distributed systems and intelligent software.

"I like software that's boring to operate and interesting to build."

Outside of the editor, I'm usually reading about system design, contributing to open-source repos, or losing track of time on a badminton court. I also write short technical notes on Medium when something I learn feels worth explaining to someone else.
