Who I Am

A little bit about me and my journey as a developer.

I'm Shazzadul Islam Shakib, a passionate Full-Stack Developer with a strong commitment to building modern, scalable web applications. I specialize in the MERN stack and PostgreSQL.

My approach combines elegant front-end experiences with efficient, secure back-end logic. I'm always excited to embrace new technologies and deliver impactful solutions that make a real difference.

When not coding, I'm studying how to escape infinite bug loops. Actually for hire.
