Hi, I'm Derbo

I build privacy tools for Linux — open source, no telemetry, no compromise.

Anonymity • Freedom • Security

---

Technology should serve people, not watch them. I write software that keeps you in control of your own machine and your own traffic: easy enough for anyone to use, transparent enough for anyone to audit.

Featured project

Katakomba — OpenVPN tunneled inside Tor, for Ubuntu & Debian

Your VPN provider sees a Tor exit node, never your real address. Your ISP sees Tor, never your VPN or where you go.

• Set up in minutes — a wizard takes the file you downloaded from your VPN provider (.ovpn or .zip) and adapts it for Tor automatically
• Self-healing — a systemd daemon fails over between accounts and providers, restarts only what is broken, and recovers after sleep
• Kill switch — while connected, nothing leaves outside the tunnel, not even during reconnections; DNS to your router is refused too
• Built against leaks — IPv6 blocking, VPN DNS applied on the tunnel, split DNS for local domains, and katakomba doctor to check it all
• Hardened — allowlisted .ovpn and torrc directives, Tor running unprivileged, root-owned deployed code
• Native GNOME interface (GTK 4 / libadwaita) in six languages, plus a complete CLI
• 600+ automated tests, none of which touch the system they run on

What I stand for

[✓] Open source by default
[✓] Privacy first — Tor, VPN, encryption
[✓] Digital sovereignty — your machine, your rules
[✓] AI in service of the individual, not the platform
[✓] No tracking. No telemetry. No compromise.

Open to collaborations that share these values.
