Built as the token-driven design system rendering this page: VT323 + JetBrains Mono + Silkscreen on a phosphor-green terminal palette, CRT boot splash, blueprint grids and scanlines. Tauri v2 + Next.js static export, React 19, Tailwind v4. 100% local and offline: no login, no server.

Online indie game · 3-repo ecosystem

My favorite project, a full online indie game built as a three-part ecosystem, each repo versioned together. An authoritative real-time backend, a desktop launcher that handles auth and updates, and the Unity game client itself. Players log in through the launcher, which boots the game and connects to Colyseus rooms over WebSockets for real-time multiplayer.
