Bio and Photos


G. Andrew Duthie, aka devhammer, is a passionate technologist with more than 20 years of software development industry experience, including nearly 10 years as a Technical Evangelist at Microsoft, where he provided support and education for developers working with the Microsoft development platform.

In addition to his work with Microsoft, Andrew is the author of several books on ASP.NET and web development, and has spoken at numerous industry conferences from VSLive! and ASP.NET Connections, to Microsoft’s Professional Developer Conference (PDC) and Tech-Ed. Andrew has been participating in the user group community since way back in 1997, when one of his co-workers dragged him out to the Internet Developers User Group in Tyson’s Corner, VA, and he’s been hooked ever since.

Andrew is currently a Lead Developer Advocate at OutSystems, where he helps software developers understand the ins and outs of Low Code software development.

In addition to his work in software development, Andrew enjoys spending time in hardware land, including developing for Kinect and .NET Gadgeteer, working with various Arduino platforms, and most recently 3D printing, using his hardware chops to do everything from blinking LEDs and making strange noises, to flying a helicopter just by waving his hands.
