Welcome to my eXtended Reality (XR) portfolio! Here you'll find my work in virtual reality (VR), augmented reality (AR), and mixed reality (MR) development.
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:
| Aspect | Hubs (Legacy) | graphwiz-xr |
|---|---|---|
| Frontend | JavaScript + A-Frame | TypeScript + React Three Fiber |
| Backend | Elixir + Phoenix | Rust + Actix-Web |
| Performance | Good | Excellent (Rust zero-cost abstractions) |
| Type Safety | Partial (Elixir dynamic) | Complete (TS + Rust) |
| Bundle Size | Large (A-Frame deps) | Optimized (tree-shaking) |
| WebGPU | Not available | Ready for WebGPU migration |
| WebTransport | Custom implementation | Native HTTP/3 support |
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
chemie-lernen.org 🔬
An open, interactive, and immersive learning platform for chemistry education.
Key Features:
- Molekülstudio: Interactive 3D molecular visualization tool allowing students to explore chemical structures in immersive VR environments
- Mozilla Hubs Integration: Virtual chemistry classroom at hubs.chemie-lernen.org for collaborative learning experiences
- Interdisciplinary VR Research: Academic research on VR cooperation in educational settings
- Open Educational Resources: Freely accessible chemistry learning materials with XR enhancements
WebXR
An introduction to building browser-based VR/AR experiences using the WebXR API and Three.js.
Technologies & Tools
I work with a variety of XR technologies:
- WebXR API - Browser-based VR/AR
- Three.js - 3D graphics for the web
- A-Frame - WebVR framework
- Mozilla Hubs - Social VR platform
- Unity3D - Game engine for VR/AR applications
- Unreal Engine - High-fidelity XR development
Project Highlights
Educational XR: Chemistry Learning
Building immersive educational experiences that make abstract chemistry concepts tangible through interactive 3D molecular visualizations and virtual classrooms. The chemie-lernen.org platform combines open educational resources with cutting-edge XR technology to create engaging learning environments.
Professional XR Solutions
Through graphwiz.ai, I share insights on AI, DevOps, extended reality, and digital sovereignty through blog content and offer consulting services for organizations seeking to build sovereign digital infrastructure. I also maintain openDesk Edu, an open-source extension integrating educational services (ILIAS, Moodle, BigBlueButton) with openDesk for sovereign university cloud infrastructure.
Innovation in WebXR
Pushing the boundaries of what's possible in browser-based virtual reality, from interactive 3D visualizations to collaborative multi-user environments. Self-hosted solutions provide privacy and customization options for organizations.
Social VR Experiments
Creating and customizing social virtual spaces where people can meet, collaborate, and share experiences in real-time. From Mozilla Hubs instances to custom WebXR applications.
Data Visualization in VR
Developing immersive data visualizations that leverage 3D space to reveal patterns and insights not possible in 2D.
