About this gig

Need a secure user authentication system with a full admin panel for your mobile app or website?


I build fast, scalable, and modern auth solutions using Firebase, Firestore, Supabase, Auth0, OAuth, JWT, React, Flutter, Node.js, and Next.js.


I deliver email or password login, phone OTP, social login, SSO, role based access, password reset, 2FA, and a clean admin dashboard to manage users, roles, logs, and analytics. Your app can include push notifications, real time updates, and secure API integration.


Perfect for Android apps, iOS apps, Flutter apps, React Native apps, web applications, SaaS platforms, fintech, business websites, and MVPs.

I also support payment gateway setup, database integration, and full stack development.



You get a secure, responsive, and professionally built authentication system ready for deployment.
