My focus is on Data driven applications and OOP systems. I have developed numerous Business database applications (both web based and desktop based) I developed an entire client server system for and EOD Stock Market Data provider. The project involved a huge back end database (SQL server 65 million+ rows) and middle tier web server (XML based web service) that published information to any interested parties (various client application developed by us or by third parties) And a front end client to interface with the web server. (Quote monkey) The entire project took over a year from planning to deployment and I lead a team of five developers the entire time. This is only one example of my past experience.
