Budget: 81 EUR Deadline: 3 days
Isolated transport service — I accept updates from Telegram (webhook or long polling), map them to gRPC calls, and proxy them to the API Gateway, without business logic inside the service. I will do it in C# (ASP.NET Core + Grpc.Net), and I will separate the protobuf contracts into a separate package for reuse. I am ready to deliver in 3 days. Please clarify: have you already chosen webhook or long polling, and is there a ready proto schema for the Gateway methods?
