I don't build demos. I build systems.
Vexy handles tickets, moderation, stats and support for VexoHost. The music bot runs separate queues per server, with Spotify, Lavalink and reconnection logic designed so nothing crashes.
In other projects I've worked on encrypted WebRTC chat, offline-first apps, accessibility, authentication and management systems used every day. The tech changes, the goal doesn't: taking the project beyond the splash screen.
