I will build a java spring boot rest API and backend
Katharina H.
About this gig
Need a reliable Java Spring Boot backend or REST API?
I will develop a clean, maintainable Spring Boot backend based on your requirements. This can be a new REST API, additional backend functionality, database integration, or a clearly defined part of an existing application.
I can help with:
- Java and Spring Boot backend development
- REST API design and implementation
- PostgreSQL and other database integrations
- Data modeling and persistence
- Validation and error handling
- Authentication and security-related functionality
- Transactions and data consistency
- Testing and debugging
- Integration with existing APIs and services
I focus on reliable backend behavior, clear structure, and maintainable code rather than simply making something "work".
Package scope depends on the complexity of your requirements. If you need multiple services, complex business logic, integrations, or a larger backend application, please message me before ordering so I can review the scope and provide a custom offer.

Yes. Larger applications, multiple services, complex business logic, or longer-term development can be handled through a custom offer after I review the requirements.
