Hey, I'm Jean-François Pustay (TheKeyblader) 👋

.NET developer with a thing for Linux — yes, both at once. I spend most of my time deep in the .NET ecosystem: backend with ASP.NET Core, desktop with Avalonia, and game-adjacent stuff with bevy.

What I'm working on

• 🔧 Enx.Systemd — A .NET library for systemd integration on Linux
• 🌐 SoftEther VPN Web Admin — A modern SvelteKit + daisyui/Tailwind interface for SoftEther VPN (PR #2227 in progress)

My stack

• Backend: .NET Core / ASP.NET Core / C#
• Desktop: Avalonia
• Frontend: Svelte + Tailwind (personal) · React / VueJS + TypeScript (professional)
• DB: RavenDB (personal) / SQL Server (professional)
• OS: Linux (CachyOS) · and proud of it

Past experiments

• Unilonia — Avalonia running inside Unity (paused — Unity's build pipeline won)
• Stridelonia — Avalonia running inside Stride (paused — code complexity fear me)

"I don't abandon projects. I pause them with dignity." 😂
