Hi, I'm Ammar Githam
Full Stack Developer based in Tokyo
I'm a full stack developer based in Tokyo with over 10 years of experience building practical, user-focused software. I work across the stack with libraries like Next.js, React, Django, Spring, and Rails, and enjoy creating clean, maintainable solutions that improve real workflows.
From modernizing legacy systems to building tools and open source projects, I take ownership of my work and care about performance, usability, and good design.
