About this gig

Need a secure login system for your web or mobile app?

Im a Senior Software Engineer with over 15 years of experience. Ill implement a professional authentication flow using best practices in security.


Whether you're using Flutter, React, Laravel, or Spring Boot, I can:

  • Email/password login and registration
  • Secure token or session-based auth
  • Role-based access (admin/user)
  • Token storage (e.g., flutter_secure_storage)
  • Forgot password and logout flows


I can connect to your existing backend API, set up Firebase Auth, or build a basic secure backend for your app. Lets secure your project and protect your users.


I work evenings ( UTC-6) and stay highly responsive, most messages get a reply within 12-24 hours and I hit deadlines reliably.
