Deploy & Troubleshoot Multi-Platform App

I need an experienced developer to take my partially completed app live on Android and iOS. Once the app is live, I also require troubleshooting support.

The app is fully developed but requires:
- Backend functionality improvements
- Integrations with identified third-party services

Ideal skills and experience:
- Mobile app deployment on Android and iOS
- Strong backend development expertise
- Experience with third-party service integrations
- Troubleshooting and debugging skills

Please include relevant work experience in your bids.
