Hello, although my profile is new, but I have a great experience in PHP/C#/SQL/Android/Java/C++/.NET development with more than 7 years in programming.
I know that you may not hire people with low reviews, I have a great experience, but I don't use freelancer much so a chat with me won't hurt.
I can take a look at the current financing app and base the modifications on it.
Contact me so we can get started.
Regards
