About me

For over 10 years my passion has been building software solutions.  My main focus is on high quality, maintainable, cost effective, well written, secure and usable software solutions.

I thrive taking on new challenges where failure is not an option and my work speaks for itself.  I demand a lot from myself as well as others that I work with.  I love working with a group of people and learning new things to expand my knowledge base.
