Midas van Oene
Senior Java engineer. Happiest when something’s being built.
I’m Midas van Oene, a senior Java engineer in Nijmegen. I work through Team Rockstars IT, which over the years has landed me at places like Kadaster and ASML; after hours I build things I actually want to use, like PodRadar and nec.quest. If that sounds like your kind of engineer, the rest of the site probably will too.
