About François

#ReadyToHelp


Independent senior developer specializing in creating applications on the iOS platform (for mobile devices such as iPhone, iPad), and Android, I offer to support my clients during all stages of their development project: needs analysis, design, specifications, development, deployment...

This is while never losing sight of my main concern, which is satisfying the needs of my clients.

Swift, Objective-C, Kotlin, Java, JavaScript, PHP, Visual Basic, C/C++ are some of the programming languages that I regularly use in my work.

I regularly work for startups, SMEs, and also for large-audience applications such as that of the FFBB (French Basketball Federation).

François' second mission for our mobile app went well. The deadlines were extended compared to the initial schedule, for various reasons, but François kept his fixed-price commitment to finalize the application. François is very professional in his communication and he knows how to be accommodating with his client. We continue to collaborate with François for the maintenance and updates of our application.

Very good cooperation with François: he is a force of proposal to share his experience on mobile apps and at the same time he adapts to the specifications requested once the decisions are made. The management of a fixed-price mission is more demanding than time-spent, and François was able to support us with a competitive proposal followed by a work of mutual trust to overcome the difficulties. Beyond the initial mission, we will therefore propose to François to continue on our project for future developments.
