About

Hi, I'm Stein!

I'm a computer science graduate with a passion for networking. I've gained experience through internships at smaller (signetbreedband) and larger (SURF) ISPs in the country. As a volunteer sysadmin at De Jonge Onderzoekers Nijmegen since 2017, I've been able to develop a broad IT skillset. During my years as a student, I've provided tech support to many clients in the Nijmegen area.
