My own software projects

Statistical Significance Calculator - A simple online calculator designed to help webmasters evaluate the results of split tests in their page changes and advertising campaigns.

Color Jam - A small open-source logical game I wrote in 2008. Written in Python, works on Windows, Linux, probably other OS's as well.

Smart Eye Trainer - A really simple Palm OS game from 2004, mostly here for the history.

NicheFinder - Keyword research software that I co-authored in 2002

my2pg - MySQL to PostgreSQL database migration utility. It is currently maintained by Max Rudensky, but it started as a small script written by me.

Commercial projects I contributed to

SOS Online Backup iPhone client - To quote PC Magazine review (Editor's Choice): "Another bonus is SOS's excellent iPhone app, which not only lets you download and view files in your online storage, but also share them via links in email."

Sana Sites - A content management system and a website development framework by ISM company. They have sold and deployed this solution successfully to a number of business customers, mainly in their home country, Netherlands.
