I have a small React + Vite app using Capacitor and Supabase. The UI is finished and must NOT be changed. I need help with a few focused technical fixes before release: - Android push notifications (FCM) are not working at all (iOS is OK). - In-app Messages and Alerts must update in real time (Supabase realtime). - Some auth/data issues: users sometimes can’t log in and saved records may disappear. Requirements: - Work inside the existing codebase only. - Minimal changes, no UI modifications. - Deliver a signed Android release APK ready for Google Play. - Provide an iOS build running in the simulator + clear steps to compile later. (I do NOT have an Apple Developer account.) Please show previous experience with Capacitor + FCM and confirm familiarity with React, Vite, Supabase and native plugins.

Having spent 20 years in the web, I happen to possess deep knowledge in Android and Mobile App Development. In regards to your project title, I can say Capacitor + FCM, React, Vite, Supabase aren't foreign terms in my vocabulary. Although I may not have the smooch of an iOS build and Apple Developer account as you might desire, I am highly proficient in fixing technical concerns with Capacitor and Supabase apps. I understand the importance of maintaining the current UI and making minimal changes that affect only what is crucial; a quality that I pride myself on. For instance, tackling your three main concerns: ensuring non-working FCM push notifications start functioning as required on Android (which is already well-functioning on iOS) , guaranteeing real-time updates on In-App messages and Alerts (Supabase realtime feature),and resolving any data or auth issues such as login problems or saved records disappearances are issues that I have dealt with before successfully. In conclusion, as a seasoned freelancer, I assure you of my complete dedication and diligence towards getting your project across the finish line error free. Providing you with a signed Android release APK ready for Google Play will be done with careful attention to detail. Finally, I am here to offer clear steps on how to better compile a future iOS build since my goal is to not just get the job done but provide you with insightful knowledge into understanding your project on a more intimate level.
