About this Gig

Looking for a clean, secure Node.js authentication API for your backend? I build production-ready REST auth systems tailored to your database.


All packages include:

  • Secure password hashing (Bcrypt / Argon2)
  • JWT token authentication
  • Input validation & structured error handling
  • Clean code architecture & environment variables


Packages Breakdown:

  • Basic ($5): Standard register & login endpoints with secure password hashing & token issuance (Existing simple DB).
  • Standard: Protected routes & middleware with EITHER email/password auth OR Google OAuth 2.0.
  • Premium: Advanced auth integrating BOTH email/password and Google OAuth, plus custom DB schema & reusable SQL query helpers.


 What is NOT Included:

To avoid any confusion, this gig does NOT cover:

  • UI/Frontend development, design, or layout modifications.
  • Connecting or integrating the API with your frontend.
  • Large enterprise distributed SSO/SAML systems.
  • Unit or Integration Testing.


Reqirements:


Please provide your existing database schema, project summary, and Google Cloud credentials (if OAuth is selected).
