Monolith to Microservices

Probien is a project with the initial purpose of being a monolith and once finished, it will be split into a microservice architecture using GRPC or RabbitMQ with event driven architecture

Lessons Learned

What did you learn while building this project? What challenges did you face and how did you overcome them? First, I had no idea how to structure the project, I come from java and have always used the MVC pattern to build services, then I decided to learn another type of desing so I create this project with domain based approach (DDD) and ports & adapters (Recomendations are welcome).

Have a proposal?
