I will fix mobile app API integration and backend errors


About this gig
Is your mobile app unable to connect to an API, returning errors, failing authentication, not receiving data, or showing outdated information?
The problem may come from incorrect endpoints, request parameters, headers, authentication, JSON handling, API responses, backend configuration, database connections, webhooks, or third-party service changes.
I will troubleshoot and fix mobile app API integration and backend issues involving REST API, Firebase, Supabase, authentication, JSON responses, webhooks, third-party APIs, and connected services. I can investigate failed requests, login API problems, missing data, timeout errors, broken endpoints, and conflicts.
My workflow is root-cause focused. I review the request, inspect the API response and backend, reproduce the problem, correct the affected code or configuration, and test the data flow.
Why work with me?
I focus on solving the actual integration problem, not temporary workarounds. You get clear communication, structured API troubleshooting, debugging, and testing. Send the API documentation, error response, screen, platform, and project details so I can assess the scope.
