Guillain d'Erceville

From the board to the byte. Same person, same week.

Now — Production AI that bills. Whisper + Claude pipeline, 9 servers, ~70% unattended. Court officers invoice on it daily.

Before — Systematic fund I built end to end. $9B/mo volume, $51M AUM. 3,500 strategies running 24/5.

Always — Reverse engineer. 10 years in the security press, cracking protocols and writing proofs-of-concept. The Grundig/Olympus dictation codec, closed since 1994, is now in ffmpeg-devel review.

What's here
Trusted-Transcription ASR hallucination firewall — 7 detectors, LLM repair, MCP server. The generic layer extracted from production.
DS2-Anywhere Cracked the Olympus DS2/DSS dictation format, closed since 1994. ~3,200 cron runs in prod. Patches sent upstream to FFmpeg.
FLAC Detective Catches fake lossless files — spectral analysis + CNN. 11K files, zero false positives.
Open-Alpha-Lab 962 trading ideas stress-tested in public. Nine survive, 789 are mirages.
PocketRoll Custom FPGA core for the 1998 Game Boy Camera.
Prometheus-Station Solar Raspberry Pi serving offline Wikipedia over LoRa.

What's not here

A legal-grade transcription platform under NDA — agent orchestration, MCP servers, 90KB rule base, 700-entry structured memory, multi-VM fleet. Architecture walkthrough available under NDA.

I publish the dead ends, not just the wins. It's the only thing that makes the wins credible.

Head of AI / AI Lead — available full-time from October 2026. guillain@poulpe.us · LinkedIn
