I fix networks, automate what I can, and build the rest from scratch.

// about

I'm an IT & Network Specialist based in Barcelona. I manage infrastructure, automate processes, and build self-hosted services that run 24/7 without intervention.

From hotel network management to running a full homelab with VPNs, Telegram bots, media servers, and game automation — I enjoy turning complex problems into elegant, automated solutions.

When I'm not fixing networks, I'm probably writing Python bots or tinkering with my Raspberry Pi.
