About Me

Crafting Code with Purpose

I'm Sanjim Mahmud — a full-stack web developer based in Bangladesh with a passion for building modern, performant web experiences. I specialize in the React/Next.js ecosystem, crafting everything from polished landing pages to full-stack applications with thoughtful architecture.

Over the past 4+ years, I've worked with startups, agencies, and freelance clients — turning complex requirements into clean, maintainable code. I believe great software is a balance of technical excellence and user-centered design.

When I'm not coding, you'll find me exploring new technologies, contributing to open source, or writing about my learnings.
