Summary
Balthazar Frolin is a full-stack engineer and product-focused consultant based in Greater Lyon, combining a formal INSA Lyon engineering background with a decade of hands-on experience across startups and R&D roles. He has led technical direction and product decisions as CTO/co-founder of a piano-learning startup and now anchors development and product refactors at Groupe Voltaire for applications serving millions of users. His work spans web and mobile stacks, AR/VR and AI/ML prototypes (including a collaborative HTV Vive/HoloLens furnishing app demoed at VRST Tokyo), plus system-level responsibilities like design systems, CI/CD and tooling migrations. Comfortable switching between coding, architecture and people management, he runs prioritization workshops and drives organizational process improvements. A classically trained pianist with chamber music training from the Conservatoire National de Lyon, he brings a creative, user-centered lens to UX and product design. Always curious, he actively explores new technologies and media to feed product ideas and research directions.
