About Emile

Developer and partner at the Calinou cooperative.

I try to contribute to public interest projects, favoring open and free solutions.

I am versatile and enjoy working on all aspects of a project, from modeling complex business domains to designing and integrating user interfaces. I seek technical challenges while paying close attention to detail and design.

Currently, I am working on:
- 🏛️ Publicodes, a declarative language for modeling complex business domains by breaking them down into simple elementary rules.
- 🚲 MesAidesVelo, a simulator to find out about bicycle purchase subsidies in France.

I have previously worked on:
- 🌿 J'agis, maintaining and developing various simulators to help citizens in their ecological transition.
- 🥥 EkoFest, a light and efficient web application to calculate the carbon footprint of events.
- 🌍 Nos Gestes Climat, the official carbon and water footprint simulator from ADEME.
- ⚖️ Catala, a programming language toolchain used to derive correct and transparent implementations from legislative texts.
