Using Generics to make a different kind of enumeration: easy to comment, and supports many types.

A biography in this little spot...sure.
I've worked at GTE HawaiianTel. I've worked at Nuclear Plants. I've worked at Abbott Labs. I've consulted to Ameritech Cellular. I've consulted to Zurich North America. I've consulted to International Truck and Engine. Right now, I've consulted to Wachovia Securities to help with various projects. I've been to SHCDirect and now at Cision.

During this time, I've used all kinds of tools of the trade. Keeping it to the more familier tools, I've used VB3 to VB.NET, ASP to ASP/JAVASCRIPT/XML to ASP.NET. Currently, I'm developing with C# and ASP.NET. I built reports in Access, Excel, Crystal Reports, and Business Objects (including the Universes and ETLS). Been a DBA on SQL Server 4.2 to 2000 and a DBA for Oracle. I've built OLTP databases and DataMarts. Heck, I've even done Documentum. I've been lucky to have created software for the single user to thousands of concurrent users.

I consider myself fortunate to have met many different people and worked in many environments. It's through these experiences I've learned the most.
