🤩
RockstarVincent Fretin is a seasoned software engineer with 17 years of experience specializing in WebXR and A-Frame front-end development, currently freelancing on projects that pair Elixir/Phoenix or Node backends with React/Solid and immersive A-Frame/WebXR frontends. He has a strong open-source track record contributing to flagship VR projects like aframe and networked-aframe—improving controller support, raycasting, and multi-user interactions—and to Plone CMS core and Pyramid tooling on the backend.

Formerly Director of IT at Illusion3D and a long-time full‑stack developer at Ecréall, he brings production experience shipping showroom and multi-user VR experiences as well as CMS-driven web systems. Notably, his contributions often target subtle but impactful issues—controller detection, collider lifecycle, and documentation generation—that improve developer ergonomics and runtime reliability.
