MiniProfiler
I continuously maintain MiniProfiler, a .NET library for profiling production applications as well as generally seeing what's going on in a code path.
Dad, Architecture Lead, Developer, Site Reliability Engineer & DBA at Stack Overflow (a.k.a. @StackExchange). Microsoft MVP. I build very fast things to improve life for millions of developers. I help build or maintain some libraries primarily in the .NET ecosystem, and help advance .NET itself. In general, I just want to leave the world a better place for the ones that follow us, and software that tens of us can improve that then help millions is the best way I've found to do that.
