I will build java spring boot rest apis and microservices

Need a reliable Java backend for your web, mobile, or business application?

I develop maintainable REST APIs and backend services using Java 17 and Spring Boot 3. I can build a new backend module, extend an existing application, or integrate PostgreSQL and Kafka into your system.

Services can include:

- Spring Boot REST API development

- CRUD endpoints and business logic

- PostgreSQL and Spring Data JPA

- Request validation and error handling

- Flyway database migrations

- OpenAPI and Swagger documentation

- JUnit, Mockito, and Testcontainers tests

- Kafka event integration

- Docker and Docker Compose setup

- Bug fixes and backend improvements

You will receive the complete source code, clear setup instructions, and documentation for the agreed functionality.

Please message me before ordering so I can review your requirements and recommend the correct package. Package prices cover only the scope stated in each package. Additional endpoints, services, integrations, security requirements, or changed requirements may require a custom offer.

Frontend development, mobile applications, cloud deployment, and real payment-provider integration are not included unless agreed separately.
