What I'm working on
Products built from scratch: side projects, tools, experiments. All self-hosted or open-source.
2025
Taking over an air-quality sensor riddled with technical debt, diagnosing it, and deciding on a full redesign. The EP6000: clean architecture, reliable measurements, WELL and RESET in its sights, and a swappable sensor cartridge built for maintenance and evolution.
2025 - Present
Web app for monitoring indoor air quality. Real-time dashboard, interactive map, PDF reports with AI analysis. Multi-tenant architecture.
2025 - Present
Tempo brings tasks, projects, meetings and documents together in a single SvelteKit app. Under the hood: Supabase and its 62 tables, a homemade Typst PDF generator, and Groq AI bounded by quotas. A guided tour of a solo project that smells of the engineer's workshop.
2023
Project manager on the DVT phase of the Elax connected device: validation, CE certification and ESD testing, between a lab in France and China.
2023
An advance-phase engagement with the agtech deeptech Javelot: defining the next generation of their connected probe, from market study to PRD.
2022
Supporting a Hermès charging accessory for Apple products, engineered by Kickmaker: Apple OEM charging integration, luxury-house finishes, full POC-to-PVT cycle in France.
2022-2023
Zaack's DUST dust sensor, in service since 2019, was going off the rails in the field: battery life under a year, measurement sensitive to humidity and temperature, false battery gauge, LoRa disconnections. Backed by a service diagnosis, I evolved it into the V2, digital sensor, integrated radio, external antenna and rethought power, without reinventing it.
