Tell us in detail about your experience in architecture design — participation in decomposing a monolith into microservices

As part of a large project, I participated in decomposing a monolithic application into microservices. The process included several key stages:

1. Analyzing the current architecture and identifying main business domains.
2. Defining service boundaries based on business functionality and data.
3. Designing APIs for interaction between services using REST and gRPC.
4. Gradually transferring functionality from the monolith to separate services while ensuring backward compatibility.
5. Implementing orchestration and monitoring systems to manage microservices.

Special attention was paid to:

• Data isolation and minimizing coupling between services.
• Ensuring fault tolerance and scalability.
• Automating deployment and testing.

This approach increased development flexibility, accelerated releases, and simplified system maintenance. As a result, the project became more resilient to changes and scalable.
