About this gig

Your AI-generated web app looked promising, but now authentication breaks, APIs fail, the database is inconsistent, or deployment no longer works.


I will diagnose and stabilize your existing web application so you can keep building with confidence.


I can help with:


React and frontend errors

Broken API calls and webhooks

Authentication and authorization problems

Database and data-flow issues

Environment variables and deployment failures

Unclear or duplicated AI-generated code

Missing validation, error handling, and targeted tests


You receive the corrected source code, a clear explanation of the root cause, and practical recommendations for the next development step.


This gig is for repairing an existing project, not rebuilding an unlimited application from scratch. Please send a reproducible description, stack, repository status, and error evidence before ordering.
