Olivier Guillet is a seasoned mobile and backend lead developer with 14 years of experience designing and delivering high-scale, secure mobile services from Nantes. He currently architects and implements the Compte Ameli iOS/Android platform serving millions of users daily, driving migrations (Objective-C→Swift, Java→Kotlin), REST services and automated testing while coaching junior engineers. His background spans technical leadership, product ownership and full lifecycle delivery—having built NFC-enabled SaaS, led a digital agency, and taught VR—so he blends hands-on coding with strategic decisions on accessibility, eco-design and compliance. Comfortable across Swift, Kotlin, Java and cloud deployments, he pairs deep engineering craft with practical ops experience (store deployments, MDM, OVH). An early games and real‑time 3D developer, he brings unusual UX and systems-thinking sensibilities to mobile architecture.
