A system to track a company ROI when that company has many different profit centers (as found in a gas station.)

This system runs on 12 computers to allow a load of 1,000 companies (each of which are likely to have about 10 staff working on the system during the day.)

Worked with the company on writing a patent to protect the technology. The basics: It includes audio and video streaming to a videowall. Click the link to see samples of what the final product is likely to look like.

Worked quite a bit to make Drupal 6 itself more usable and secure. I submitted several security issue reports to the Drupal security team.

An Ubuntu (Linux) based CMS built in C/C++ which interfaces with the Cassandra NoSQL database.

Because of the way the software is built, this CMS truly has the capability to grow horizontally. It supports any number of front end computers which can supports heavy incoming load. The server itself can reside on a back-end computer. The system includes many back-end processes that run on separate computers to not cause trouble on the front-end computers. The Cassandra nodes are all expected to run on their own separate computers.

The OpenSource core modules include a firewall manager, a watchdog to check the health of your entire cluster, an administrator front end, 50+ plugins to select per website functionality, a multi-computer crash impervious lock system, database backup (on top of the Cassandra replication), advanced RPC daemon, many built in security features (anti-pounding, instant block of IP addresses on entire cluster, Fail2ban, Tripwire, rkhunter, settings of Postfix, Apache, and Bind9 tweaked on installation to ensure PCI compliance, anti-virus), CSS compiler/compressor, REST, OAuth 2, and more.

I wrote a CSS preprocessor ("compiler") which I wanted to use to compress CSS files from C++. So the implementation is in C++ and it offers a library which does all the preprocessing as required.

The compiler is more or less replicating the Sass compiler. It supports variables, includes, multi-level blocks of CSS, etc. It also compresses better than many existing CSS compressors ("minifiers").

The compiler is also stringent on the syntax which makes sure that your source is correct. It also has the ability to expand or select rules so the final CSS works on more browsers (you could compile separate CSS files each for a specific browser.)

The compiler comes with a large set of tests which covers 100% of the code to make sure most cases are covered (see the "COVERAGE" link under Maturity).

All the features are also fully documented through Doxygen.

In 1995, I worked on SkyTRACK, a telestrater system that would display graphics behind a weather caster.

I worked on the patent, research, and implementation of the software tracking system which was artificial intelligence (albeit basic).

The system was sold to Weather Central which offered it with their system to many (100+) television stations around the US.

I have a video with Steve Raleigh, the weather caster of KRON 4 at the time. This is an early version. Steve says my name near the end of the video. The station had around 1 million viewers at the time.

I worked on the Eagle Eye, including development, bug fixing, writing unit and integration tests, and running performance tests.
