You will get a reliable Java Spring Boot REST API or backend bug fix
Project details
Need a reliable Java or Spring Boot backend fix or REST API without unnecessary complexity? I have 9+ years of Java and backend engineering experience. I will review your requirements, work with your existing codebase or create a focused backend component, and deliver maintainable source code.
Depending on the selected package, I can help with:
• Spring Boot REST API development
• Bug diagnosis and fixes
• MySQL and Redis integration
• Request validation and error handling
• Third-party API integration
• Basic unit tests and API documentation
You will receive source code, a clear summary of changes, and setup or run instructions.
Please message me before ordering if the work involves a legacy codebase, production outage, microservice architecture changes, AWS deployment, or an unclear scope.
