Home Server
Personal infrastructure made up of a web server (a 2008 laptop), a reverse proxy (NPM) and a firewall (pfSense) running Suricata in inline mode. Additionally, within the admin network, a server running Proxmox allows hosting a wide variety of services on virtualized machines.

Segmented Network Architecture with IPS
Design and implementation of a segmented home network with multiple defense layers. Inbound traffic first passes through Cloudflare as a reverse proxy, WAF and DDoS filter, then through a firewall (pfSense). It has three network interfaces (DMZ, Servers, Admin) in addition to WAN, each running an independent Suricata instance as IPS for intrusion detection per segment. Traffic first passes through the reverse proxy hosted on my network, which decrypts HTTPS traffic so it can be re-inspected by Suricata. The guest network is completely isolated.

Official Arch Linux Mirror
Maintenance of an Arch Linux distribution mirror. The server syncs repositories automatically via rsync and is securely exposed to the internet through the DMZ.

Lately I've been training for the Buenos Aires half marathon and taking care of my plants. I also maintain this website and an Arch Linux mirror — all self-hosted on my own servers with proper security measures in place.
