Rockstar🎓
Top SchoolJean-francois Cunat is an experienced ingénieur logiciel based in Rennes with eight years (and much longer industry tenure) delivering front-end and multimedia solutions for Orange and France Telecom. He has deep practical expertise in video playback, SmartTV and Chromecast receivers, Electron/Vue.js apps and HTML5 players, and contributed PlayReady DRM improvements and unit tests to the widely used dash.js project.

Comfortable across full-stack concerns, he pairs legacy systems knowledge (XSLT, Java) with modern JS stacks and analytics-driven feature rollouts. Known for pragmatic, test-focused fixes and incremental improvements, he blends hands-on coding with product-minded engineering in international contexts. Trained as an engineer in telecoms and electronics (Polytech Nancy, Dublin Institute of Technology), he brings strong systems thinking to media and web platform challenges.
