Summary
👤
Senior🎓
Top SchoolJean-elie Barjonet is an engineer-turned-founder with 11 years of experience building and leading web engineering teams and data-driven simulation projects. He combines hands-on full-stack development and architecture work (Node, Typescript, React) with product leadership—having led engineering at PayFit and Vendredi, recruiting and mentoring teams while shipping scalable platforms and CI/CD. More recently he applied his modeling and data governance expertise to territorial resource planning at The Shift Project and the French ministries, before founding Navigable to map global resource and energy flows for European sovereignty. He excels at translating complex policy and domain constraints into maintainable software and visualizations (D3.js), and has a knack for embedding typability and immutability into legacy codebases to improve reliability. Educated at ESIEE Paris with an Erasmus in interaction design at Chalmers, he mixes systems thinking with UX sensibility—often surfacing operational insights that non-engineers miss.
