I build C# desktop software and run my own infrastructure from home. Most of it happens late at night.

About
I'm a developer from Chaidari, Athens. Originally from Ioannina. While I'm in high school, most of my real learning happens at my desk after midnight: building desktop apps in C#, breaking my server, and then figuring out why it broke.
I got into coding because I wanted software to work exactly how I wanted it to. That turned into three years of .NET, WPF, WinForms, a Proxmox homelab, Tailscale tunnels, and way too many late nights chasing LACP bonding issues.
I build real things for real use cases, not tutorial projects. If it doesn't solve an actual problem I have, I'm probably not building it.
