Featured Projects

graphwiz-xr 🚀

A complete rewrite of the Mozilla Hubs ecosystem using TypeScript + Rust

graphwiz-xr is a modern VR/Social platform delivering high-fidelity, browser-based virtual reality without installation barriers. This ambitious project reimagines the entire Hubs ecosystem with next-generation technologies for maximum performance and scalability.

Technology Stack:

• Frontend: TypeScript, React 18, React Three Fiber, Three.js r160+, Vite
• Backend: Rust microservices with Actix-Web, SeaORM, PostgreSQL
• Networking: WebTransport (HTTP/3) for next-gen real-time transport, gRPC, Protobuf
• Editor: Tauri desktop app for native performance with React UI

Key Improvements over Original Hubs:

Architecture Components:

• Hub Client - Main VR client (TypeScript + R3F)
• Admin Client - Dashboard for management
• Reticulum - Backend microservices (Rust): Auth, Hub, Presence, Storage
• Spoke - Scene editor (Tauri + React)

Performance Targets:

• Backend: P50 < 10ms, P99 < 50ms latency
• Frontend: 60 FPS desktop, 90 FPS VR
• Network: < 5KB/s per client (positions)
• Bundle: < 2MB initial load
