Worked on two software development contracts simultaneously (aprox 60 hrs/wk) during this period. All assignments were successfully completed on time or ahead of schedule.


Lead Delphi Developer/Oracle DBA to Haas Publishing Co.

Initially worked on the backend technologies supporting the ApartmentGuide.com web-site. Utilized Delphi and Oracle and Visio and MS-Project.

  • Built data export program that could run automatically on a daily basis and export data for the various portals which Apartment Guide provided content for, including Yahoo!, Lycos, MSN Home, and other.
  • Developed full requirements document and developed initial pilot for an automated e-mail routing system that routed visitor inquiries to various parties within the organization which would free up two positions within the company once implemented.

Transferred to the RAX development team, which maintains an in-house system developed in Delphi and Oracle for tracking distribution of all publications of the company in 60+ markets throughout the nation. The software tracks all publications and inventory, drivers, driving routes, store locations, racks in the store, service frequency, and which publications go in each pocket on the racks.

This allowed the project to continue and be supported with only one developer and DBA as opposed to three full-time developers, one Q/A, and two DBA’s.

  • Revamped a faulty architecture by eliminating a largely repetitive cut-and-paste approach and introducing fuller use of object oriented and design techniques.

  • Helped revamp some areas of application to process data in batches and dramatically boosting user productivity.
  • Introduced numerous custom built components to the system to bring about more consistent underlying implementation and user interface uniformity throughout the system.
  • Built multi-platform installation scripts with InstallShield and wrote Installation manual for end user as well as full troubleshooting guide for field support technicians.
