Request : experienced app dev - well paid assignment topic

I'm looking for a experienced app developer who can write code for a previously designed app.
The app will display info from users based on location,

The app will be for commercial use so it has to be quite secure and I do require a clean code witch worked without big issues.
We offer good money for the right person.

If this is not the right place for this request, I apologize. I'm in a little crisis because I don't know where to start looking for developer 😀

If you have what it takes, or if you have some questions, please send me a line

Thanks.
