Every musical device starts as an idea and ends up as thousands of concrete decisions: what the player touches, how it responds, what the software lets them do, what gets left out. The wrong ones usually come back later as rework, bad reviews or support emails. I help you get them right, and then I build them.
I make firmware and desktop software for musical devices, often as the one person covering both sides, and I enjoy helping shape the product along the way. 15 years in the field, musician, PhD in HCI. I can take on all the software or just one part.
Before freelancing, I spent 9 years as the software developer at a small French instrument maker, writing all the software for its products, which I also co-designed and helped showcase through demo videos and music: Sylphyo (electronic wind instrument with a wireless receiver), Anyma Phi (semi-modular physical modeling synth) and Loom (multi-touch MPE ribbon controller, finished as a freelancer this year).
Since 2025, as a freelancer:
- Firmware and guidance for a team building their first MPE controller.
- Firmware features and Ableton Live remote script for an MPE controller already on the market.
- High-fidelity prototype of a desktop app for a soft robotics simulation framework, from user research to usability testing.
Looking for: freelance work on musical devices or other interactive products, day rate, available from November 2026.
