Over deze dienst

Is your Java Spring Boot REST API returning errors, unexpected responses, or failing to communicate correctly with another service?

I will troubleshoot and fix issues in your existing REST API and backend application.

I can help with:

REST endpoints

HTTP errors and responses

Request and response handling

JSON serialization/deserialization

Validation

Spring Boot controllers and services

JPA/Hibernate integration

Database-related API issues

Third-party API integrations

Backend business logic

With 11+ years of software development experience, I have worked extensively with Java, Spring, REST APIs, databases and enterprise applications.

I focus on identifying the root cause of the problem and implementing a practical solution in your existing codebase.

Please contact me before ordering if your API issue involves multiple services or a complex integration.
