Hello, I’m Hiren Kapuria, an experienced Android developer with expertise in building secure, modern applications. I can create or modify your mobile app with a focus on user authentication to ensure both functionality and safety. I will implement authentication using proven solutions like Firebase Authentication (email/password, social logins, phone OTP) or custom JWT/OAuth2 flows, depending on your needs. The process will follow Android’s latest security best practices, including encrypted communication, secure credential storage, and robust session management. Alongside the backend integration, I’ll design clean and user-friendly login, signup, and password recovery screens following Material Design principles, ensuring a smooth experience. Strong emphasis will be placed on protecting sensitive user data and making the authentication flow intuitive. Deliverables include updated or new source code, a debug APK for testing, and a release-ready AAB for deployment. I will also provide clear setup notes so you can easily manage authentication keys and extend features later, such as role-based access or 2FA. Why me: I bring years of experience working with Android, security, and user flows. My goal is to deliver a solution that is secure, stable, and compliant while being simple for your users to navigate. Best regards, Hiren Kapuria
