About Raphael

Senior Software Engineer
C++/Qt and JavaScript Expert

Graduate Engineer from Mines with over 10 years of experience, you are facing a true enthusiast of logic and code, ready to take charge of your applications from start to finish, from design to production.

Here, no fuss about technical stacks or legacy code.
What I enjoy is the technical challenge.

An algorithm to optimize in C++? An interface in Qt/QML? A complex Progressive Web Application in Vanilla JavaScript? A mobile application in ReactNative? A backend in PHP? A compilation script in Bash? A test in Python? It's already done!

So, if you have a meaningful project, a cohesive team, and you want to do good for your applications, don't hesitate to get in touch.

Caution, limited availability!
