About Cyril

From design to deployment, including development and testing, I support you on your iOS and web projects.

Initially a web developer in 2008, honing my skills on personal projects and internships during my Master 2 Professional degree (PHP, MySQL, Go, MongoDB, Docker, SEO), I became an iOS developer at OVH in 2010. I have acquired solid experience in Apple technologies: Objective-C and Swift, Fastlane, applications and SDKs, publishing source code in open-source or private mode.

I have worked on iPhone, iPad, MacOS applications and Apple TV and Apple Watch prototypes.

I enjoy working with UX/UI designers to successfully complete the design of mobile applications.

Interested in entrepreneurship, I also have several projects underway and upcoming!
