Do you write automated tests for the APIs?
Yes! I highly value code reliability. Depending on the package, I write robust unit tests using JUnit 5 and Mockito to ensure the endpoints function correctly under various scenarios.

I will need a clear description of the problem or feature, your database schema (if applicable), and access to the existing source code if it's a bug fix or integration task.
Will the project be ready for deployment?
Yes, I deliver clean source code. I can also prepare Dockerfiles for your Spring Boot application and manage database changes using Liquibase, making your deployment process much smoother.
Can you handle microservice communication?
Yes! I have hands-on experience setting up direct and efficient communication between microservices using synchronous REST calls and Spring Cloud OpenFeign.
