About Me

I am Leo Montero Nylén, a technical student and developer focused on reliable systems and practical automation. I've been coding since I was 12, building everything from simple IDEs to full-stack homelab clusters.

I design and run self-hosted infrastructure, build secure APIs, and ship products from prototype to production.

  • Secure API design & JWT auth
