I'm a Senior Customer Success Engineer at Duende Software, where I help teams succeed with Duende IdentityServer. I've been working with .NET for over a decade, and I love writing about ASP.NET Core, C#, and web development. When I'm not coding, I'm probably traveling with my wife Nicole or going on long walks with our two dogs.

As a content creator and what some might classify as a community educator, I’ve spent the better part of my professional career blogging and creating fun community assets. Long-time readers may have noticed the site got a revamp recently, and a new coat of paint. A lot of work is invisible, but it’s already having a positive impact.
