About this gig

Having an issue with your REST API, backend code, or database?

I can help you troubleshoot and fix backend-related problems in an existing application.

I can help with:

REST API bugs and errors

Java and Spring Boot backend issues

PostgreSQL and SQL problems

C#/.NET backend issues

CRUD operations and backend functionality

API testing and troubleshooting

Debugging existing backend code

Adding or modifying small backend features

Database-related backend issues

Swagger/API issues

My process is simple:

  1. Understand the issue and expected behavior.
  2. Review the relevant code, API, or database logic.
  3. Identify the cause of the problem.
  4. Implement the appropriate fix or feature.
  5. Test the result and explain what was changed.

Please provide the error message, requirements, relevant code, or project details before starting so I can understand the scope of the work.

I value clear communication and honest expectations. If an issue is outside the agreed scope or my current experience, I will let you know before proceeding.
