Bug Fixes for an E-Commerce Mobile App

I am looking for an experienced React Native developer to complete several minor fixes and functionality checks for an existing e-commerce mobile application. The app is already fully developed, and I have complete access to the source code, backend, and documentation from the previous developer...
