I'm looking for a talented Android app developer to create an app that allows users to log in, select services, and make payments. The services in question involve booking appointments.

Key Features:
- User Login: The app should support multiple user login methods including Email/Password, Social Media Login, and Phone Number OTP.
- Service Selection: Users should be able to book appointments through the app.
- Payment Integration: The payment system needs to accept Credit/Debit Card and Google Pay.

Ideal Skills:
- Proficient in Android app development
- Experience with integrating secure and reliable payment systems
- Skilled in implementing various user login methods
- Knowledge of creating service selection interfaces
- Familiarity with developing booking service apps

Please note that the service provider side of the app should allow for service providers to login, host services, and receive payments. I am looking for a professional who can handle this project efficiently and effectively.
