Tim Tyrrell’s Summary

My main interest is working on an Agile team with an ALT.NET mentality. Ideal development environment would be ASP.NET MVC and C# with Fluent NHibernate/NHibernate for the data access layer. I am "cutting my teeth" on Domain-Driven Design, Test-Driven Development, and Behavior-Driven Development.

I am active in the local .NET community; I am the secretary of the NW Arkansas .NET User Group, the co-founder of the Wal-Mart .NET User Group, and am registered in the INETA (International .NET Association) Regional Speakers Program.
