## 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

- Daily driver: Ryzen 7 9800X3D · RTX 5080 · hand-built custom keyboard
- Italian (Native) · English (Fluent) · German (Conversational) · Spanish & Norwegian (Basic)

## Homelab
Two-node setup built to enterprise patterns at personal scale. **Zero open ports** — all external access via Cloudflare Tunnels and Tailscale. Every service containerised, every entry-point proxied, every failure logged. The UNRAID box, **[Nargothrond](https://github.com/Quinta0/Nargothrond)**, is fully documented in its own repo — hardware, Docker stack, network segmentation, and traffic-flow diagrams.
| Component | UNRAID Server (Nargothrond) | Proxmox Node |

| **CPU** | Intel Core Ultra 5 225 | Intel Core i7-8700 |
| **RAM** | 48GB DDR5 5600MHz | 32GB DDR4 |
| **Storage** | WD Gold 14TB + 2× WD 12TB parity array + 2TB NVMe pool | SSD (OS) + SATA pool |
| **OS** | UNRAID 7.3.1 | Proxmox VE 8 |
