Have you ever worked with gRPC?

gRPC is a modern framework for remote procedure calls (RPC), developed by Google. It uses HTTP/2 for transport, Protocol Buffers for data serialization, and supports multiple programming languages. gRPC enables efficient and fast message exchange between microservices or between client and server.

An example of using gRPC: defining a service in a .proto file and generating code for the server and client. This is convenient for building distributed systems with clearly defined contracts.
