I have been using C since 1998. I am familiar with its standard library, and with tools such as gdb, electric fence and valgrind.
Visual Basic
I have experience building VB 6 applications, as well as COM components for use from ASP.
Computing

Twisted
Developer, March 2002–present
Twisted is an open-source asynchronous networking library for Python. My contributions include the FTP client, an inetd(8) implementation, a Win32 version of the reactor, documentation, and many other features.
