Full Stack Developer for App Maintenance

I’m looking for a full stack developer to maintain and upgrade an existing app already in the App Store. The work includes improving app functionality, updating and integrating more APIs, and adding AI features to enhance the user experience. The app is built with React Native and uses AWS, Expo, and Firebase. I’m looking for someone who can help keep the app stable, scalable, and up to date while supporting ongoing improvements.
