Hey, I'm Erzen Krasniqi, a product and systems engineer.
For the past 4 years I've been building products end to end: interfaces, APIs, data models, infrastructure, and the lower-level systems underneath. Currently at 91life2024, a digital health platform.
The rest of the time I build in the open18 repos: a Rust operating system with its own bootloader, a cross-platform agent fleet controller, and a self-hosted deployment platform.
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.
