Professional Experience

PRS Technologies, Inc. Consultant 2001 - present

Have written software solutions for several clients both in the U.S. and abroad. Notable activities have included:

  • Successfully writing and implementing conversion programs for an Elite Billing System merger for an existing law firm client that merged with another firm.
  • Written numerous electronic bills in various format including Ledes and Legal Advisor using both Informix 4gl and a version of Ledes that runs from a UNIX shell script that is called from Elite for Windows.
  • Coded several custom reports for both marketing applications and Elite billing applications, including participation on an attorney profile that combined data from various sources and presented it on the firm's intranet - thereby eliminating hours of manual effort to assemble this information each month.
  • Participated in a successful data recovery effort for a banking database that was lost after the computer crashed. The entire Informix database was restored onto another computer that I had to set up to mirror the original crashed server.
  • Coded interfaces to many cost recovery systems for clients including a cost recovery program that loads Federal Express charges from a Fedex website into Elite and then generates prepaid vouchers for each invoice to account for electronic payments. Have also automated cost recovery into Elite at several firms for systems such as Equitrac, Copitrak, and Carpe Diem.
  • Wrote web-based data entry/query forms using Informix 4gl to dynamically generate HTML and Javascript. Created forms to insert/display data in an Informix Online database to HTML in a Linux environment. Modified other existing programs to meet display standards determined by the client.
