About

Building the web,
one commit at a time.

I'm Slyman Harfoush, known as Yohan — a full-stack developer from Syria with a passion for building clean, performant web applications that solve real problems.

I work across the full stack — from crafting intuitive frontends with React and TypeScript, to designing robust backend systems with Node.js and PostgreSQL. I care deeply about code quality, user experience, and shipping things that actually work.

When I'm not coding, I'm exploring new technologies, contributing to open source, or thinking about how to make software feel more human.
