Mobile App API Integration

I need a developer who can cleanly integrate a third-party API into my existing mobile app, which is available on both iOS and Android. The goal is to expose the new data endpoints throughout the app, handle authentication, and make sure every call is efficient and secure.

The current code-base is well-structured and under version control; you will receive access to a dedicated branch along with the API documentation and sample keys. Once the endpoints are wired in, I expect you to write or adjust unit tests, verify the integration on real devices for both operating systems, and push a merge request for review.

Deliverables
• Fully implemented API calls with error handling
• Updated UI where new data appears (if needed)
• Passing unit tests and a quick usage note in the README

I’m looking for someone who has already shipped at least one production-ready API integration for both platforms, is comfortable with Git, and can start as soon as possible.
