Have you worked more with monolithic architecture or microservices?

Most often, I worked with monolithic architecture, where all application components are in a single codebase and deployed together. This simplifies development and deployment in the early stages, but over time can lead to challenges with scaling and maintenance.

I have experience with microservices in projects where the application is divided into independent services, each responsible for its own business logic and capable of evolving separately. This increases flexibility and scalability but requires organizing interactions between services, managing their state and infrastructure (for example, through APIs, message queues).

In Node.js, microservices are often implemented using REST API or gRPC, while monoliths are built as a single application on Express or NestJS.
