Veelgestelde vragen
Which Spring Boot version do you use?
I use the latest stable Spring Boot 3.x with Java 17 by default. I can also work with Spring Boot 2.x and Java 8/11 if your existing project requires it.
Do you provide source code?
Yes, you'll receive complete source code with Git history, documentation, and deployment instructions. The code is fully yours.
Can you work with my existing codebase?
Absolutely. I can integrate new microservices into your existing system or refactor monolithic code into microservices.
What databases do you support?
PostgreSQL, MySQL, Oracle, MongoDB, and Redis. I have deep production experience with all of them, including query optimization.
Will you provide tests?
Yes. All my code comes with unit tests (JUnit 5, Mockito) and integration tests (TestContainers). I aim for 80%+ test coverage.
Do you offer ongoing support?
Yes, I offer post-delivery support for bug fixes within revision limits. For long-term maintenance, we can discuss a separate arrangement.
