Frederic Abraham · public work
16 public repositories, newest first. Scroll, and the vine digs back through the work — past Respeak, past 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 live 3D playback — every algorithm machine-verified against a real cube model, and every case openable in a cube you can turn yourself.
Tauri + Rust · 198 of 617 commits
A native cockpit for running a flock of coding agents at once. Every session gets a real terminal, and Claude and Codex stream back phase, context use, cost and permission prompts — so a dozen agents are as easy to mind 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 gates every pull request — including the flaky slow-driver startup that used to break it.
WebGPU · transformers.js · no upload
Preview, clean up, vectorize and export your logo — 100% 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. No README yet — the commit log does the talking: a copy wizard you step through, and a release train that refuses to ship from the wrong branch.
engraved notation · tap a note to hear it
The hymnal people actually sing from: engraved music that re-breaks to the screen and keeps the words their room, notes you can tap to sound, and paging that follows the playlist or the order of service.
887 tests · 27 files · offline-first
The offline half of the hymnal — an honest download state, dark mode applied before the first paint, and a church-service stepper that locks while a service is actually running.
one scroll signal · eight set-pieces
This site. Nuxt + Content, Lenis + GSAP, and a GLB head flown through an ASCII post-process — camera, lights, gaze and set-pieces all derived from a single scroll number.
Directus · similar-object matching
An upload desk for a centenary archive: contributors add objects, the app surfaces ones that look like something already catalogued, and the token handling keeps a long cataloguing session from quietly dropping.
v2.0 · rolling 60s buffer
Records the last x seconds of a Twitch stream so you can replay the thing you just missed. Configurable replay volume, 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 desk behind the church hymnal — table of contents, an engraved-music carousel and change notes. The congregation tells me on Sunday morning when it breaks.
paper · pretrained models
The published version: pretrained models plus the decoding algorithm, released alongside the paper “Utilizing GANs for Stable Structure Generation in Angry Birds”.
Tatort, then Experte
A chat game contracted for 100k concurrent that went live at 18,000; then tech lead on a RAG platform that has to cite every answer it gives. The side projects never stopped.
Science Birds · playability-scored
The thesis itself: GANs trained to invent Science Birds levels, scored on whether the structures they design actually stand up.
Maastricht
Two years to actually understand the machine learning I had been using on the side. Specialised in generative models; graduated at 8.25.
johannischer-kirchentag.de · 94 commits
The event site for the Johannischer Kirchentag — programme, dates and registration, baked to Cloudflare. Five years of on-and-off work with the community; I am its second-largest contributor.
Nothing from me in this window — my 94 commits run Jun 2020 to Apr 2025. The site is live and others keep it moving.
hall of fame · auto hyper-params
Generic genetic-algorithm environments for the JVM — a hall of fame, selection-probability shaping, and automated hyper-parameter search.
TU Berlin
Multi-agent systems at GT-ARC; the identity-management apps behind ~47,000 students and 9,000 staff at RWTH Aachen. The root of the whole thing.
