Christophe Jossart

Full stack developer, open source contributor

Based in Lausanne, Switzerland

I graduated in Computer Science and Graphic Design.

I build web platforms and the integrations around them: AI gateways and LLM features with Symfony AI, decoupled frontends with Astro, React and GraphQL, headless CMSs like Payload, and 3D on the web with Three.js. As a full stack developer, I am also involved in the infrastructure, with Docker and Kubernetes, and I work with CDNs such as Fastly, Cloudflare and CloudFront. I have been working with Drupal since 2008, mostly on the backend, and I still contribute to it.

When I'm not coding, I mostly enjoy hiking with our dogs 🐾 as a member of the Swiss Alpine Club, but also snowboarding, reading tons of comic books, growing things in our collective garden, painting and photography.
