About

Mehedi

I'm a Computer Science graduate who finds satisfaction in turning complex problems into clean, well-structured code. My work spans the full stack — from designing RESTful APIs with proper validation and error handling to building responsive frontends that people actually enjoy using.

I've integrated payment systems, AI services, real-time webhooks, and courier APIs into production applications. I care about the details: sensible architecture, readable code, and systems that handle edge cases gracefully.

When I'm not writing code, I'm usually exploring new technologies or figuring out how to make something work just a little bit better.
