-## About Me
-
-> Hi — friends call me **Quinta**. I'm an Economics student at USI Lugano and a self-taught systems engineer who's been running homelab infrastructure since 2020.
->
-> My setup spans bare-metal Proxmox clusters, DNS and domain management via Cloudflare (AAAA + Tunnels), Pangolin/Traefik reverse proxying with auto-TLS, and a full media & music automation pipeline.
->
-> On the academic side I'm deepening my understanding of microeconomics, macroeconomics, game theory, and quantitative finance — finding more overlap with systems thinking than you'd expect.
