I have designed, implemented and maintained web applications, gui applications, e-commerce systems, automated test suites, compilers, developer tools, discrete event simulations, financial models, commercial apps, in-house apps, etc. I also perform consulting, system administration and database administration.

I'm the creator of the Cobra programming language which is open source and has an active community. Cobra combines the best features from many languages including Python, Objective-C, Eiffel and C#. My presentation at the Lang.NET Symposium 2008 was recorded. This is my second major compiler in additional to several prototype interpreters.

I'm the original creator of Webware for Python, an open source suite of web frameworks. I successfully passed the project to another developer before starting my next project (Cobra).

I have designed and written two object-relational mappers (ORM). One is an open source ORM for Python called MiddleKit. The other is a .NET one, private to a client, originally created before NHibernate and others were available and/or mature.
