Extensive development experience with C# .NET, networking and asynchronous applications (since 2009). Worked on frameworks, multiplayer Unity3D games and game servers. I'm looking for a C# or Rust project to develop programming related tools, frameworks and technology - the stuff that others programmers use.
Also I would be interested in a project related to high load or low latency distributed server solutions (e.g. game servers). I like refactoring, optimizing and automating stuff.
Another kind of suitable project would be a game related to simulation and automation like Factorio or ONI.
