Today, your host, Jeffrey Palermo is speaking with Jared Parsons, the Principal Developer Lead on the C# Compiler Team. Everybody tuning in probably uses his code on a day-to-day basis! Jared started out at Microsoft 15 years ago as a Developer; moved on to become a Senior Developer; then Principal Developer on Midori OS; and most recently, the Principal Developer on C# Compiler Team, which he has been with since 2014.


In this episode, Jeffrey and Jared are taking a look at what the DevOps environment looks like for the C# Compiler. They take a look at how the source code is organized, the configuration process, some of the challenges they’ve run into and how they’ve solved them, as well as Jared’s career journey with Microsoft.


The C# Compiler is a highly depended on, complex, widespread piece of software — so tune in to get all the behind-the-scenes insight with Jared Parsons!
