Charles Wiebe and John Hansen are Microsoft .NET software architect/designer, for Windows Forms and ASP.NET solutions.
Charles specializes in the application layer – Web Parts and other ways of building GUI’s. John specializes in high capacity object oriented systems and connectivity.

John and Charles are co-developers of Jetfire – a .net open source, multi-user, application domain specific language (DSL) with syntax heavily based on C# and Java. The goal of Jetfire is to allow power users to quickly and easily develop and deploy applications, in much the same way as Excel allows powers users to quickly develop spread sheets.

Their latest project is Jazz - a compact, modular framework that allows new, or existing, applications to easily employ roles, states, ACLs and void safety. Jazz allows complete workflows to be implemented in only a few hundred lines of C# or VB code.
