I build products end to end: the model, the backend, the app, and the store listing. Today that means a music app I founded, an open-source trading stack, and the AI tooling that helps me ship both.

Jam Jam is a free chord, key and tempo detector with an editable songbook. Drop an audio file or play into the mic: on the web, detection is free and unlimited in your browser, with no account. It also comes as an Android app and an iOS public beta. Try the detector · Overview · Android · iOS beta

• On-device AI: chord recognition, beat tracking and stem separation, exported to ONNX and run in the app.
• Built end to end: React Native app (Expo, Kotlin native modules), Astro website, Supabase backend, Python audio service, public REST API.
• Open parts: jam-jam (how the detector works, and where to try it), jam-jam-assets (versioned models and sounds, with checksums and licenses) and jam-jam-api-examples (API guide and examples).

Project	What it is
freqtrade-ultimate	Production fork of Freqtrade for Hyperliquid. Shared data cache across bots (75 % fewer API calls, measured live with four bots), walk-forward and CPCV validation, liquidation detection.
frequi-ultimate	Multi-bot dashboard for Freqtrade: fleet comparison, risk overview, strategy tooling. Vue 3, Pinia, ECharts.

Both are maintained with the Freqtrade France community.

• claude-tools: my Claude Code setup. Every task goes to the cheapest model that can do it (Haiku, Sonnet or Opus), a hook enforces the routing, and reusable work becomes a tested skill. Fewer tokens, same reliability.
• vault-core and pp-connect: the security-critical parts of Prompt Pipeline, open for audit (Argon2id + AES-256-GCM vault, relay layer with anti-SSRF guards and secret redaction).

Ingénieur logiciel, diplômé de l'ESIEA, je construis des produits de bout en bout. Je suis le fondateur de Jam Jam, une application qui détecte les accords des chansons grâce à une IA qui tourne sur l'appareil. Je développe aussi freqtrade-ultimate, une plateforme de trading algorithmique open source suivie par la communauté Freqtrade France, et claude-tools, ma boîte à outils pour travailler avec des agents IA à moindre coût.
