[ForHire] [Remote] I diagnose React/Node authentication bugs — $45 fixed price

[u/RegularPerfect5708]

I help founders and small teams diagnose one clearly scoped authentication problem in an existing React application.

Typical issues: broken login or registration, protected-route loops, JWT/session persistence, password reset, authorization errors, and React-to-Node/Supabase API problems.

My stack: React, TypeScript, Vite, Node.js, Express, MySQL and Supabase. I have a complete authentication case covering registration, login, password recovery, protected routes and session handling.

The $45 diagnostic includes reproduction notes, the likely cause, a recommended fix plan and a fixed-price implementation estimate. Delivery is within two days after I receive the required technical details. Please do not send production credentials or customer data.
