FAQ
Do I need to have an existing Kafka cluster set up?
Not necessarily! For development and testing, I can set up a local Kafka environment using Docker. If you already use a cloud provider (like Confluent Cloud, AWS MSK, or Aiven), I can seamlessly integrate the microservices with your existing cluster.
Can you integrate Kafka with my existing Spring Boot monolith?
Yes, absolutely. I have extensive experience in the banking sector refactoring legacy systems. We can gradually introduce Kafka to decouple your monolith and start transitioning towards an event-driven architecture without breaking your current features.
Do you provide documentation and testing for the code?
Yes. I focus heavily on code quality. All packages include clean, commented code. For Standard and Premium packages, I also include a README file with clear instructions on how to run the services, and I can include Unit Testing (TDD) as an extra if required.
What if I am not sure which package fits my project?
That is completely fine! Please send me a direct message with your business requirements or the problem you are trying to solve. I will gladly help you figure out the best architectural approach before you place any order.
