Building great applications together

Passionate freelance software developer, I'm always striving to improve. I'm commited to provide the solution that best suits your needs. No more, no less.

Who am I ?

Hi there, I'm Romain Bertholon, a passionate French software developer!

I live near Lyon, France. My experiences lead me to work on different subjects such as digital forensic, finance and telecommunications, in France and the Netherlands. My main expertises are in C++ 11/14 and Python, but I'm opened to any languages and technologies.

I had the opportunity to get a 4 weeks Java training, and to use various other technologies, such as C# or QT. Currently, I feel very interested in Web Development using NodeJs and NoSQL, especially MongoDB.

I'm an advocate of TDD, because I like to provide THE most adapted solution. I enjoy working with continuous delivery processes because it allows constant feedbacks.

On my spare time I like to draw with a dip pen and China ink, walk in the forest, and spend time with my fiancée. I also enjoy biblical studies.
