Backend dev, homelab operator, security tinkerer.

I've been programming since I was 10. Now I'm studying Cyber & Computer Technology at Aalborg University Copenhagen, working part-time in IT at Eksponent, and running a homelab with 30+ self-hosted services. Outside of tech: bouldering, working out, and bartending.
