I will fix react typescript nodejs API or postgresql bugs
Theo P.
Over deze dienst
A stubborn bug should not become a rewrite.
I will reproduce, diagnose, and fix issues across modern full-stack applications built with React, TypeScript, JavaScript, Node.js, Express, REST APIs, and PostgreSQL.
Common work includes broken UI state, forms, authentication, API failures, CORS, async logic, database queries, deployment or build errors, and regressions between the frontend and backend.
My process:
1. Reproduce the issue and confirm scope.
2. Identify the root cause.
3. Implement the smallest reliable fix.
4. Test the affected workflow.
5. Explain what changed and how to prevent recurrence.
You receive working source changes, a concise diagnosis, and test notes. I do not support WordPress or Shopify theme work in this Gig.
Please message me before ordering with the error, expected behavior, stack, and repository or files so I can confirm the right package.

Veelgestelde vragen
Do you need repository access?
Repository access is preferred for proper reproduction and testing. A Fiverr ZIP upload can work for a small project.
Will you work directly in production?
Only when scope and access are appropriate. Staging or a reproducible local environment is safer and usually faster.
What if the issue is larger than the package?
I will stop after diagnosis, explain the scope, and propose a custom offer before expanding the work.
Do you guarantee every third party service can be fixed?
No. I can fix your integration code and configuration, but I cannot control vendor outages or inaccessible systems.
