Hello, I’m Erzen.
A software engineer in Prishtina, Kosovo. I build complete systems, from the lower-level software underneath to the interface a person actually touches.

I started by taking software apart on the web. That curiosity kept moving into APIs, deployment systems, AI infrastructure, a Rust operating system, Unity and Roblox games, and the research tooling behind two peer-reviewed optimization papers.
I care about software that feels obvious: fast, quiet, and built to last. Good interfaces and strong engineering should make the machinery feel simple.
