Building the world

The 3D world couldn't load — it needs WebGL and a connection to the three.js CDN.

01 — Origin

Würzburg, then everywhere

I study Human-Computer Interaction at the University of Würzburg — a BSc, an exchange year in Computer Engineering at UT Austin, and now an MSc that finishes in February 2027.

The desk is the constant. Everything else drifting out there — the pyramids, the canals, the alpine lakes — happened between commits.

02 — Work

Spatial computing, shipped

At SAP I build Apple Vision Pro and web experiences for the Business AI Platform: a cross-platform Joule Work Desktop demo deployed to the showroom, a Vision Pro app for AI-driven remote data center audits that replaces auditor travel, and the Sapphire C-Suite Experience rebuilt as a BTP web app.

Plus 25+ enablement sessions and technical demos on stage, worldwide.

Teaching machines to speak, and to supervise

A Conversational Model of Texas German. An endangered dialect, 13.6 hours of transcribed interviews, 177 speakers. The translation stage scores 0.21 on a purpose-built dialect-distance metric — real held-out human transcript scores 0.24.

The Clone as Boss. My master's thesis: what happens when your own manager appears as a photorealistic AI clone, life-size in your room, and delivers bad news.

The workshop

Small, sharp things I build because I needed them — and an accessibility app that won the Apple Swift Student Challenge 2025 out of more than 10,000 submissions.

DyLexAid simplifies reading for people with dyslexia: text-to-speech with synchronized word highlighting, customizable formatting, and a distraction-free reading mode.
