Paul Usul Ekelund

I have been building games in C# and Unity since 2009. Gameplay mechanics, multiplayer, shaders, lighting, backends, and the tooling that holds it all together. Almost all of it in small teams, taking projects from prototype to release.

My favourite work is profiling, performance and getting memory under control. That, and juice.
