David is a developer at Microsoft, working on Roslyn, also known as the C#/VB compiler and IDE tools, in Visual Studio.
A developer for the last 20 years, David has had experience in lots of different languages and environments, from cgi-bin scripts in Perl, to genetic algorithms in VB3, and Windows applications in COBOL. A series of terrible decisions, clearly, but he learnt in the end and now spends most of his time developing with .NET in C#, and enabling other developers to do the same.
David is mostly interested in C#, good design and Lego Technic and Creator Expert cars. He can be found tweeting at @davidwengier, streaming at https://twitch.tv/davidwengier, helping to organize the DDD Melbourne conference, and on about a dozen different slacks and discords.
