Is there experience working with gRPC?

Yes, I have experience working with gRPC. I used it to build high-performance microservices in Go, providing efficient bidirectional streaming and strict typing through Protocol Buffers.

gRPC allows easy description of services and methods, automatic generation of client and server code, which speeds up development and reduces the likelihood of errors.

Example of a simple Go service with gRPC:

// Service definition in a .proto file
service Greeter {
  rpc SayHello (HelloRequest) returns (HelloReply) {}
}

// Server implementation
func (s *server) SayHello(ctx context.Context, in *pb.HelloRequest) (*pb.HelloReply, error) {
    return &pb.HelloReply{Message: "Hello " + in.Name}, nil
}

I am also familiar with setting up TLS, authentication, and monitoring gRPC services.
