About Guillaume

I am a specialist in mobile application development from scratch. I study with the client the best possible solution for his project, by studying the UX/UI path. Then I build the architecture and if needed I can manage a technical team.
I mainly develop in Flutter today, to attack the iOS and Android market. I also have a background in connected objects if ever it is a need for your projects.
