I’m looking for short and medium term engagements that push my existing skills to the limit and afford opportunities to expand upon my knowledge. I’m not interested in being the smartest person in the room. I would rather learn from them as their strong right hand.


My skill with Microsoft-based technologies come with years of professional experience, and my familiarity with free/open source tech comes from years of home use and running my own website.
