BILL SCHOOLFIELD
Principal


Email Bill

When a business owner takes the extra time and trouble of tracking down a ‘long-lost’ IT consultant from 10 years ago to do work for him because he’s talented, persistent, and trustworthy, you know that consultant’s special. With nearly 30 years of experience in all aspects of software development, Bill has designed and developed new systems, maintained and supported existing systems, worked in quality assurance, and provided client support and account management. His experience primarily has been in technical computing associated with oil and gas exploration, with an emphasis on client/server and Intranet-based systems.

Bill’s innovation and creativity was recognized by his previous employer when he received awards for developing an application for ‘geosteering’ horizontal wells (which received a patent), and designing and developing an Intranet application for the management of well log data.

At iSpark Bill wears numerous hats: helping to manage the iSpark and BillMax businesses; developing the BillMax application, engaging and supporting BillMax clients; business development; IT consulting and administration for iSpark clients; and developing new applications for oil and gas exploration.

Bill earned his Bachelor of Science degree in Geology from the University of Georgia, and has both lived overseas and traveled to many countries to support clients.
