Related Work Experience

Web-Folio, LLC
Position: CTO and Senior Programmer, January 2004 to present
Web-Folio is a webhosting and picture handling service which enables anyone with a modicum of computer experience -- or even just a willingness to try something new -- to create and maintain a polished, professional web site featuring hundreds of pictures. The back-end gallery software is a code fork from the locations.org location scout webhosting site, where I did extensive programming for three years and continue to handle systems administration and tech support. I wrote the front-end user interface, which puts all of the back-end power in the hands of those nontechnical users, entirely from scratch and continue to add features to both ends in response to our clients' needs and our direction.

As Chief Technical Officer, I review existing practices and new hardware and software for its applicability to our practices and procedures as well as provide technical direction and support for our customers.

As Senior Programmer, I not only manage most of the coding but also manage all bugfix and feature releases to ensure code continuity and a smooth upgrade for our clients each time.

Independent Consultant
Position: Consultant, January 1992 to present
I am a freelance computer consultant and web programmer well versed in systems administration, networking, database, security, programming, and productivity programs and concepts. I have experience with many operating system flavors and am intimately familiar with Solaris UNIX, Linux, and Microsoft Windows and DOS and do most of my web work in PHP and MySQL.

While not in a full-time contract I take on multiple positions; I welcome home and small office users (for whom I have done troubleshooting, installations, upgrades), larger corporations (for whom I can put in part- or full-time hours, on- and off-site, for a full-time delivery), and programming contracts (both Sys Admin and web site back-end).
