I already have both Android and iOS apps coded and a live server environment, but the two are not yet talking to each other end-to-end. I need the core wiring completed so the apps can send and receive data reliably, handle authentication, and surface any server-side errors gracefully. Here’s the scope I’m aiming for: • Review the existing codebases and identify the current network layer or SDK used for HTTP/WebSocket calls. • Connect each required screen or feature to the relevant server endpoint, adding or adjusting lightweight APIs if something is missing. • Implement secure request/response handling (tokens, headers, SSL) and basic offline/timeout fallbacks. • Produce a build for Android (APK/AAB) and iOS (TestFlight IPA) that I can install and verify. • Provide a concise integration note outlining any new endpoints, credentials, or environment variables I’ll need for future updates. Everything else—UI tweaks, major backend refactors, or new features—can wait until this first integration milestone is signed off. If you’re comfortable jumping into an existing codebase, troubleshooting JSON payloads, and turning around a working build quickly, this should be a straightforward engagement. Payment: released only after the Android app is live on Google Play and the iOS app is live on the App Store (published and available to download).
