Hello!
I have done multiple projects like this one before and I was interested in making another one. I am an experienced C#, Python and PHP programmer. The front-end will be done in C# Form Applications, and the back-end will be done in C#, Python or PHP, according to your own choice. As I've mentioned before, I've done very similar if not the same projects before, with the same messaging, contact list and emoji system.
Thank you for this amazing offer and I hope I get chosen.
Best Regards,
Paul.
