Dec 93 – Aug 96 CompuServe Columbus, OH Software
Engineer § Web Mall – Major task was to implement the online ordering system. This consisted of HTML screen design, database design, and converting from HTTP to secure HTTP. The conversion was done by upgrading web servers and installing security certificates on the SPRY safety web server, this later moved to Microsoft’s IIS. Other parts of this project included dynamically creating HTML pages using database information (Microsoft SQL Server), writing user orders to the database, and adding banners using server side includes. Form processing was done using C++ cgi-bin scripts. Other parts of the architecture required inter-server communications using RPC. § Webguide – Lead for “TV Guide for the Web”. This task included building the prototype, converting the existing interface to dynamic database (Microsoft SQL Server) driven HTML using Cold Fusion, and writing the back end data entry and editorial utilities. Moving this into production required estimating load requirements, determining the number of machines required, and ensuring the proper set-up of the production environment. § Web Shareware – Worked as in-house architectural consultant for this and several other Web based products while at CompuServe. § CompuCard Store – implemented the communications library. This library retrieved information from a daemon and re-packaged it for the application. Served as the CompuServe contact to CompuCard for the transaction requirements, and was also responsible for all transaction versioning. § Visa Usage Credit – A promotional offer. If the user signed up for a Visa card, they would get free time on CompuServe’s service. Implemented the user interface for the product using a proprietary CompuServe GUI library. The task required that a proprietary database be populated with a set of pre-defined passwords. The application challenged users for passwords, retired old passwords, recorded successful user id’s, and issued free time through CompuServe’s billing server. The database itself was updated on a regular basis, and a set of statistical and informational reports were built using this data. § E-minder - This product is a CompuServe mall add-on allowing users to specify dates with special significance and then remind them via e-mail when those dates were near. The main task was to enhance the mall ordering system to support purchasing directly from an E-minder message. This made it possible to have E-minder automatically send flowers for Mother’s Day, for example. This project was also used to train a new member in the CompuServe mall architecture. § All projects at CompuServe required source control using Visual SourceSafe, formal code reviews, and team effort. |

Apr 93 – Dec 93 Nationwide Insurance Columbus OH Intern § Net Present Value project – Converted an economist’s report describing projected earnings based on age, sex, education, etc. into a computer model using AI techniques.

This was then compared with the claim in question to determine if it were reasonable or not. |
