Hi,
I have studied C, C++ in middle school as major. And I have developed C, C++ programs for 7 years.
So I have confidence in developing C, C++.
You also want developer who has Javascript and Python skills, but don't worry. I have a wealth of experiences of developing web projects using Javascript and Python. About 4 years experiences.
By the way, my friends are also very good at programming. Nowadays they are biding projects on web developing based on modern frameworks.
If you want I will introduce you my friends.
I hope to be your project developer.
Thank you.
