The software featured a barcode system for all labor and materials. The system supported a workforce of over 100 mechanics and tracked both productive and nonproductive time.

He created an Internet alternative to the ILS in 1995, Internet Parts Locator Systems (IPLS).

He was instrumental in the IS management of an FBO, working closely with management to create reports and make software changes that streamlined the process of recording productive and non-productive time. When the FBO was caught in the liquidity trap of 2001 he took on the task of working with creditors in a non bankruptcy scenario, allocating the remaining funds to pay off debt at 52 cents on the dollar.

This process used a custom program to manage the work of four DAR’s for a period of nine months and successfully recertified over 40,000 parts.
