Caught me, C#. Library quality has improved a lot in ten years, the language feels modern, and one of Go's biggest advantages, single binary cross-compile, is way less relevant now that dotnet standard installs easily on every OS I care about. I was prototyping some code that needed to talk to OpenAI, Slack, and Linear and the result was.. fast and extremely readable inline async code. I've interacted with these APIs in Go as well and by comparison, ultra clunky.

We're a video game studio as well using C#, and while game programmer != backend programmer, I can at least delegate small fixes and enhancements out to the team more easily.
