Jure Rastić

Developer, Team lead, FLOSS enthusiast

Currently

Director of Software Engineering @ Infoart, Croatia

Summary

Seventeen years writing software, and still at it. Built payment systems that started as nothing and grew to serve millions — learned a few things along the way. Now I take old tangled code and make it simple again. I work with Java, Python, sometimes Flutter, and whatever else the job requires. I prefer the solution that costs little and works well. I like FLOSS and leading people without making them miserable.
