Android Security App - "Intruder Selfie" with On-Device AI, Stealth Protection & Decoy Mode.

I am looking for an experienced Android developer to create a high-end security MVP. The application is designed to identify unauthorized users through local AI face verification. The app must be "intruder-proof," run silently in the background, and ensure that all evidence is securely delivered to the owner. ​Key Functional Requirements: ​1. Trigger Mechanism: ​The app must activate immediately upon every "Screen ON" event or device unlock. 2. ​Stealth Capture (Photo & Audio): ​Silent Photo: Capture a high-quality photo using the front camera without any UI indication, shutter sound, or flash. ​Audio Recording: Silently record 20 seconds of ambient audio immediately after the trigger. ​3. On-Device Face Verification (Google ML Kit): ​Verification must be performed 100% locally on the device using Google ML Kit. ​No Cloud APIs (Azure, AWS, etc.) are allowed to ensure privacy and zero recurring costs. ​Compare captured faces against a registered "Master Face." ​4. Security Logic: ​If Owner Identified: Immediately delete the captured photo and audio file less than 1s ​If Intruder Identified: * Stealth Storage: Save the photo and audio to the app’s internal private directory (Hidden from the public Android Gallery). ​GPS Logging: Capture precise GPS coordinates and timestamp. ​Email Alert: Send an immediate SMTP email containing the photo, audio file, and location map link. ​5. Advanced Protection Features: ​App Lock: Access to the application settings must be protected by PIN, Pattern, or Biometrics. ​Self-Protection Alert: If an incorrect PIN is entered 2 times to access the app, it must capture a photo and send a "Security Breach Attempt" email alert. ​Decoy Mode (Fake Interface): The app must support two PINs. The "Master PIN" opens the real app. A "Decoy PIN" opens a fake, innocent interface (e.g., a simple notes page) to mislead anyone forcing the owner to open the app. ​Technical & Integration Details: ​6. Custom SMTP Configuration: Include a settings section for users to input their own SMTP Server, Port, and Email credentials for background delivery. ​7. Persistence: Must be implemented as a Foreground Service with Battery Optimization Bypass and all necessary Accessibility/Overlay permissions to ensure the process is never killed by the OS. ​8. Offline Queue: Alerts must be queued and automatically sent once an internet connection is established. ​Deliverables: ​Complete and commented Source Code (to be pushed to my GitHub repository). ​Working APK for testing. ​Basic documentation for SMTP setup and Master Face registration.
