Decode Android APK & Firebase Data Recovery

# Android APK Reverse Engineering & Firebase User Data Recovery Expert Needed **Project Description** I have an existing Android application (APK file), but I no longer have access to its original source code. The application is currently connected to Firebase. I am looking for an experienced Android Reverse Engineering and Firebase developer to help me analyze the application and recover the technical information necessary to manage and potentially rebuild it. **Main Tasks:** 1. Analyze and decompile the Android APK using JADX or other professional reverse engineering tools. 2. Identify the application's architecture, Firebase configuration, authentication methods, and API integrations. 3. Determine which Firebase services the application uses (Authentication, Firestore, Realtime Database, etc.). 4. Help recover or re-establish authorized administrative access to the Firebase project, where possible. 5. Export existing user email addresses, phone numbers, and available user IDs from the Firebase project using authorized access. 6. Deliver the exported user data in CSV or JSON format. 7. Recover as much readable application code and functionality as technically possible. 8. Provide a technical report explaining the findings, limitations, and options for rebuilding the application. **Required Skills:** - Android APK Reverse Engineering - JADX / APKTool - Java / Kotlin - Firebase Authentication - Firebase Firestore / Realtime Database - Firebase Admin SDK - Android Application Recovery - API Analysis **Important:** I am the authorized owner of the application and am seeking recovery of my own project and data. All access and exports must use legitimate administrative permissions. **Expected Deliverables:** - APK technical analysis report - Recovered/decompiled code where possible - Firebase integration assessment - Authorized user data export (email, phone, UID) - Recommendations for restoring or rebuilding the application Please explain your experience with similar projects, your proposed approach, estimated completion time, and fixed project price.
