## 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.

- 🎓 BSc in Economics @ USI (in progress) · 2 yrs BSc Informatics completed
- 🏗️ 5+ years SysAdmin & IT consulting · 6–10 production servers · 90%+ uptime
- 🖥️ Daily driver: Ryzen 7 9800X3D · RTX 5080 · hand-built custom keyboard
