Work History

Retiree Vounteer Work
Since retiring from Fedex in December, 2013, I've worked as a telecommute web developer for Caritas Virginia (CARITAS) and the History of Computers for Learning and Education (HCLE), an online museum.
My work for CARITAS was to make some bug fixes and complete some development when their funding ran out for a paid developer.
I am currently developing a Catalog Maintanance System for HCLE's inventory. This includes access control and a search function.

I worked 28 years at FedEx developing software and providing support for Application Performance Management (APM). I worked in the Software Development, APM and Information Security departments there.

I started in Information Security and supported RACF, dial-in connections and automated some of the manual departmental tasks. At the time we were focusing on security for the mainframe computers running IMS on MVS, as well as the CMS and TSO environments.

I then moved to the aircraft weight and balance support team. There I developed a PC based clone of the mainframe system and managed distribution of the software and data files throughout the U.S. before TCP/IP was available on the PC. We used Watchdog PC Security to restrict access to the PCs and control access to the files on the PC. Distribution was managed through dial-up modem connections and scripts developed using the modem software. This application is still used throughout the world by FedEx.

I then moved to a client/server area where our team developed the first FedEx Web Portal, followed by a scanning application to collect package movement data for packages in the Memphis Hub. This application used industrial scanners, keypads and printers. My team was also responsible for configuring the connections and hardware between the servers and the Hub sort area. This application used Informix, then Oracle databases. The response time between the scanning the barcode and the audible response from the server was less than 1/2 second. The second phase of this project was to put InfraRed receivers throughout the hub to permit near-real-time collection of the scan data from the SuperTrackers in the Hub. I lead this project from start to finish.

In the same client/server area, I began handling the scan data collection from around the globe and generating revenue generating data for the packages as they moved through the sorting facilities. Several million scans were collected each day. Processing was done without a database. However, for data validation a MySql database was built to allow quick reference to the raw scan information. Web pages were built using PHP, to permit monitoring of the data collection processes and Unix servers. This monitoring provided at-a-glace view of the up/down status of each component as well as clickable links to see the details of any problems.

My final eighteen months at FedEx I was primary support for Application Performance Monitoring (APM) for over 7500 servers and over 300 applications. When I came into this group, APM monitoring was with CA's Wily product. During my last year we tested and began the migration to AppDynamics APM solution. During this time I oversaw integration of AppDynamics into the application, access control to the APM data and assisted the development teams to identify performance issues with the application, network and databases.
