About this gig

If your OAuth login is failing, JWT authentication is broken, or user sessions are not persisting on Replit, your application is effectively unusable. Users cannot log in, APIs reject valid tokens, and protected routes become inaccessible.


I specialise in fixing authentication systems, including OAuth flows, JWT token handling, session management, and backend API security issues in Replit-based applications.


Most auth failures are caused by misconfigured token signing, incorrect redirect URIs, expired sessions, CORS issues, insecure storage handling, or broken middleware logic. I dont guess I trace the full authentication flow from login request to token validation and fix the exact point of failure.
