Hello Sir, I have noticed your project and I think I could be fit for the job.
First of all, I speak a bit of German,so there shouldn't be any problem for the two of us to interact.
Secondly, I am an experienced C++ programmer, especially in the field of game programming. I have a github that I update fairly regularly, if you want to see some of my code.
I am motivated and I have always given a high value to the quality of the work and the respect of delays. Your project would not be an exception.
I would be glad to be able to contact you so that you can give me any specific details about the project.
Sincerely eager to work with you, Guillaume Roy
