Rahman Hamim · Sylhet, BangladeshFullstack engineer, frontend to AI.

React interfaces, Node services and data behind them, AI features on top, and AI in my daily workflow to ship faster. Motion is the habit I bring along: the editor below is a typed React component rendering live from JSON props.

What I do

One developer, four things I actually ship.

Every cell below is live. Click, drag and press: the demos are built with the same tools I would use on your project.

Click the segments and the switch

Frontend

Interfaces with feel. Real state, real transitions, accessible by default, not just layout.

The service behind the screen: APIs, auth, data, queues and deploys, built so the frontend never has to guess.

AI engineering

LLM features done carefully: streaming, tool calls, retries and evals. And AI in my own workflow, every day.

The interest that sharpened the rest: timelines, easing and springs you can reason about, rendered frame by frame.

I started in frontend, building websites and interfaces. Then I kept going down the stack: services, data, deploys, and lately the AI features on top.

Today I ship products end to end and use AI in the loop every day, both as a builder of LLM features and as a tool in my own workflow. Motion is the part I do for love; it taught me to think in frames and functions, and I would rather show you a working thing than a slide about it.
