I have two production-ready Android apps that need a round of solid bug fixing and a few finishing touches before the next release. Both projects are already live in Firebase and use Firestore Database as the main back-end, yet several core features are not behaving as expected. Current pain points • Sign-in and registration screens keep refreshing or hanging, so the user flow breaks. Google location fetch issues • All categories of notifications fail to arrive on some devices. • Google / Gmail authentication was added but never finalised. • Firebase settings need a proper review to be certain everything points to the right Firestore project and keys. • Deep links that should open specific in-app pages currently route to the launcher screen. • The admin panel is fully coded; it simply has to be deployed on my hosting and connected to the same Firestore instance. • A handful of very small UI or wording tweaks remain. What I’ll hand over Full Android Studio projects, existing admin panel codebase, Firebase console access and hosting credentials. You can work in Kotlin or Java—whatever fits the current code style—just keep the structure clean. Deliverable A fresh build of both apps with every issue above resolved, the admin panel running live on my server and all changes committed back to the repository. I’ll verify that: – Sign-up / login complete in one step without page refresh loops – Push notifications and in-app messages arrive consistently – Google sign-in works for every tested account – Deep links open the correct activity every time – Admin panel syncs to Firestore with no console errors Once those boxes are ticked, we’re done. If this sounds like a quick win for you, let’s get started.

I’m an Android developer with 6.5+ years of experience, and I regularly handle production bug-fixing, Firebase troubleshooting, and release polishing for live apps. Your issues are well-defined and absolutely fixable within a focused stabilization cycle. I’ll review both Android projects end-to-end, starting with Firebase configuration to ensure Auth, Firestore, FCM, and OAuth keys are correctly aligned with the intended project. I’ll fix the login/registration refresh loops, complete and stabilize Google/Gmail sign-in, and resolve location-fetch issues using proper lifecycle and permission handling. For notifications, I’ll debug FCM delivery, background handling, and device-specific failures to ensure consistent arrival. I’ll also correct deep link routing so links always open the intended in-app screens instead of the launcher. The admin panel will be deployed on your hosting and connected to the same Firestore instance, with all console errors resolved. Remaining UI or text tweaks will be completed cleanly without disturbing existing logic. I’m comfortable working in Kotlin or Java, following your current code style and keeping the structure clean. All fixes will be tested and committed back to your repository. Final delivery will include fresh builds of both apps, a live admin panel, and confirmation that login, notifications, Google sign-in, deep links, and Firestore sync work reliably. This looks like a solid, straightforward cleanup—happy to start immediately.
