Developed a set of unix scripts that use ImageMagick to automatically generate custom individualized Photo ID cards for player backpacks, and photo trading cards (e.g. baseball cards) for Sunnyvale Alliance youth soccer teams.

Developed a custom text file format, LaTeX style sheets, and Perl scripts to enable quick entry of song lyrics, chords and metadata, and typesetting of custom songbooks and lead sheets featuring song lyrics and guitar chords for musicians, and powerpoint slides for lyrics display from weekly song lists.

Created a mobile-accessible website for a volleyball league (IVL) to record match results and automatically generate weekly printouts that show overall season standings, weekly matchups and the previous week's results.

Built a custom website with touch-screen enabled web applications: family photo albums, NOAA weather forecasts, music videos, and embedded Flash games for kids.

Continuous developer of web based applications since 1995, beginning with a simple Make Your Own Home Page CGI script hosted at MIT and listed in Yahoo while it was still http://akebono.stanford.edu/yahoo/

Continuous administrator of linux systems beginning with kernel v0.99 and Slackware on running on a 486.
