Student. Builder.
Infrastructure Nerd.
I’m a developer from Chaidari, Athens, Greece - originally from Ioannina. While attending high school in Chaidari, I spend my free time building desktop apps in C#, running self-hosted servers, and exploring VPN protocols, game modding, and anything else that looks interesting.
- Writing .NET desktop apps in Visual Studio 2026 Insiders
- Running Proxmox, Jellyfin & Plex on Ubuntu servers
- Experimenting with VPN tech & LACP network bonding
- Modding BeamNG.drive & Minecraft in my spare time
- Building NSIS installers for pro app distribution
