Hi PH, I'm Quy, a .NET developer from Vietnam, and I build FxMap

Hi everyone, I'm Quy. I write backend code in .NET, mostly microservices, and I'm new here.

I make FxMap, an open-source library that came out of a boring problem I hit again and again: an order has a UserId, and I had to call the user service, batch the ids and copy Name and Email back into the response by hand. FxMap lets you describe that once with a fluent API, and then it fetches the related fields from the service that owns them, over gRPC, NATS, RabbitMQ, Kafka and a few others.

It's a small side project that grew slowly, it is not a startup, and I'm still learning how to talk about it. I'd love to hear how other people handle data that lives in different services, and what you'd want from a tool like this.

Nice to meet you all.
