I am Rayhan, a full-stack developer focused on building fast, maintainable web products with clean architecture and great UX. I like turning complex interfaces into simple, predictable experiences that scale.

I work end-to-end across frontend and backend, from product planning and UI architecture to APIs and deployment. I care about performance, clarity, and the long-term health of a codebase.
