17 public repositories, newest first. The further you scroll, the further back it goes: past Respeak and the M.Sc., down to a genetic-algorithm library from the last year of the B.Sc.

41 F2L · 57 OLL · 21 PLL
A CFOP reference with 3D playback. Every algorithm is machine-checked against a real cube model, and every case opens in a cube you can turn yourself.
Tauri + Rust · 198 of 617 commits
A native desktop app for running many coding agents at once. Every session gets a real terminal, and Claude and Codex report their phase, context use, cost and permission prompts, so a dozen agents are as easy to keep track of as one chat.
Rust core · TS shell · Tier-2 E2E
File sync with a Rust core and a TypeScript shell. A native end-to-end suite runs on every pull request, including the slow-driver startup case that used to make it flaky.
Workers · Durable Objects · live board
A digital scorecard for mini-golf courses. Guests scan a QR code at the entrance and play hole by hole on their own phone, with no app and no account, while a big screen keeps the live leaderboard: podium, ties and who just climbed.
WebGPU · transformers.js · no upload
Preview, clean up, vectorize and export your logo, entirely in your browser. No uploads, no sign-up. Background removal runs on WebGPU.
first co-authored commit
Everything above this line was built with it. The commit weeks jump from single digits to forty-plus, and four new projects start within four months.
v0.20.1 · 306 commits / 52w
An events tool in Python and Vue. It has no README yet; the commit log shows a step-by-step copy wizard and a release process that refuses to ship from the wrong branch.
engraved notation · tap a note to hear it
The app people sing from in church: engraved sheet music that reflows to the screen while keeping room for the lyrics, notes you can tap to hear, and paging that follows the playlist or the order of service.
887 tests · 27 files · offline-first
The offline part of the hymnal: a download state that reports what is really stored, dark mode applied before the first paint, and a service stepper that locks while a service is running.
one scroll signal · eight set-pieces
This site. Nuxt and Nuxt Content, Lenis and GSAP, and a GLB head rendered through an ASCII post-process. Camera, lights, gaze and set-pieces are all derived from a single scroll value.
Directus · similar-object matching
An upload desk for a centenary archive. Contributors add objects, the app points out ones that look like something already catalogued, and the token handling keeps long cataloguing sessions from dropping.
v2.0 · rolling 60s buffer
Records the last x seconds of a Twitch stream so you can replay what you just missed. Configurable replay volume and a redesigned settings popup.
self-hosted · most-starred repo
Self-hostable room and resource booking. The static pages are pre-rendered at build time and baked straight into the frontend image.
Directus · Vue · Vuetify
The editing tool behind the church hymnal: table of contents, a carousel of engraved sheet music, and change notes.
paper · pretrained models
The published version: pretrained models and the decoding algorithm, released with the paper “Utilizing GANs for Stable Structure Generation in Angry Birds”.
Tatort, then Experte
First the SWR Tatort game, built for 100,000 concurrent players and launched with 18,000. Then tech lead on Experte, a RAG platform that cites every answer. Side projects kept going alongside.
Science Birds · playability-scored
The thesis itself: GANs trained to generate Science Birds levels, scored on whether the structures they design actually stay standing.
Maastricht
Specialised in generative models and graduated with 8.25. Part-time alongside it at RWTH Aachen, just across the border, on identity-management apps for about 47,000 students and 9,000 staff.
johannischer-kirchentag.de · 94 commits
The event site for the Johannischer Kirchentag: programme, dates and registration, deployed as a static site on Cloudflare. Five years of on-and-off work with the community; I'm its second-largest contributor.
No commits from me in this window. My 94 commits run from Jun 2020 to Apr 2025; the site is live and others keep it going.
hall of fame · auto hyper-params
Generic genetic-algorithm environments for the JVM, with a hall of fame, selection-probability shaping and automated hyper-parameter search.
TU Berlin
Student developer at GT-ARC for most of the degree, working on multi-agent systems. Bachelor's thesis on genetic algorithms for shop scheduling.
