Hey, I'm Erzen Krasniqi, a software engineer in Prishtina, Kosovo.
For the past 4 years I've been building products end to end: interfaces, APIs, AI systems, data models, infrastructure, and the lower-level software underneath. Currently at 91life2024, a digital health platform.
The rest of the time I build in the open23 repos: a Rust operating system, AI application builders, coding-agent tools, self-hosted infrastructure, and digital products for Kosovo.
I also build game systems in Unity and Roblox, and co-authored two peer-reviewed papers on metaheuristic optimization and reproducible benchmark tooling.
I like software that feels obvious. Fast, quiet, and built to last.
