About Yoni

From design to launch, including development and testing, I will support you on your mobile application projects.

Specializing in native Android development (Kotlin, Java), I also master cross-platform techniques (React Native and Flutter).

The goal is to make a single development compatible with both Android and iOS, thus reducing your costs, respecting your budget, and offering you maximum visibility to your future users.

With over ten years of development experience, I have been able to support and advise my clients on high-volume applications. Therefore, I am particularly sensitive to the quality and maintainability of the code produced.

Do not hesitate to contact me, I will be happy to advise you on the most suitable technical choices for your needs.
