PHP

Implemented a database-rule-driven product configurator, as part of a migration of the Rig-A-Lite site to Drupal 7. Rig-A-Lite provides lighting solutions for hazardous environments, such as light fixtures for off-shore oil rigs. Their old product configurator did not enforce legal configuration choices - such as which ballasts require fuse blocks, or are not available with metal halide lamps, for example - which caused order processing aggravation for their worldwide sales reps and customers.

The configurator is iframe'd into Drupal, leveraging the company's old sophisticated full-custom PHP/MySQL/JQuery CMS backend to populate its new Drupal front end. The new rules data is edited in a valid-configurations Excel table, and imported into the CMS, to drive the product configurator user interface.

As of this writing, most products haven't been converted to use the new configurator. That was a design feature, that the new system would allow them to use both old and new product configurators side by side, as they gradually converted products.

Pattern Blocks are used in early math and just for fun. Great for drawing mandalas, tilings, and tesselations. Originally written as a toy for my daughter in 1998, this is my most popular app by a landslide. Latest version features full-browser resizing, better email, hundreds of backgrounds, and keystroke shortcuts. Now with Art Gallery for kid-safe sharing!

Mandalar is PatternBlocks for mobile! PatternBlocks is now released as a mobile app. See Mandalar. Still in Adobe Flex - all web/mobile platforms are cross-operable.

MathToybox is the new social home for my kids' games, featuring PatternBlocks Art Gallery, direct access to the Triaxle Scoreboard, and room to grow in a kid-friendly design.

Originally Flex3 / PHP, now rewritten in jQuery / PHP.

Triaxle is a puzzle game based on hexagonal instead of square neighbors. Score history is tracked both locally and versus other users, via a server database.

This was the first complex program I wrote in ActionScript 2 - complete with soundtrack, fairy lights, gameplay, PHP backend - big learning experience.

Now with direct access to the Triaxle Scoreboard.

CrossPlan / Cross-Suite is a site for social integrated circuit block-level layout editing. I built database, intelligent integrated circuit editor, design history management, integrated instant messaging, and the whole Drupal site, for The Shearwater Group and Pinebush Technologies. This site is not public - please contact me if you need a demo. Alpha release only - the recession put this project on hold.

FlexSimpleStats tracks semantic usage statistics within my simulators - what users actually do with them. These days, one can use Google Analytics for this, but SimpleStats predates GA by years. The server side of SimpleStats is implemented in PHP and MySQL, called by client-side Java, Flash, or Flex. This tool browses and charts CourseWare historical usage data, back to January, 2004. Originally implemented in Flash, now in Flex.
