Hi, I'm Khayruzzaman Himel — a Junior MERN & Frontend Developer from Rangpur, Bangladesh. I'm currently completing my Diploma in Computer Technology at Rangpur Polytechnic Institute, and I've been coding and building production-grade web projects for over a year.
I care deeply about craft — the kind of subtle details that separate a good site from a memorable one. I combine a frontend-first approach with fullstack competence: building authentication flows, REST APIs, database schemas, and now, integrating AI & LLMs into product experiences.
When I'm not coding, I'm studying design, dissecting Awwwards-level interactions, and leveling up — to make every next project better than the last.
