Chief Information Officer (Interim Chief Technology Officer)

OasisJet Fuel Inc. & OasisJet, Inc.
OasisJet was a contract fuel company that partnered with Fixed Base Operators (FBOs) to provide low-cost jet fuel. OasisJet s pricing model allowed corporations, air ambulance companies, cargo companies, and private citizens to purchase JET-A fuel at prices cheaper than unleaded gas. As I had initially worked on the OasisJet software for a consulting firm, they brought me on full-time to continue development and lead their IT strategy.As a startup company, my position at OasisJet encompassed various aspects of business, technology, and the application of technology to solve business problems and drive efficiency. Efficiency improvements included the streamlining of information, data, and reporting flows to accounting and administration. The data flow implementation I designed gave us the ability to make decisive business decisions more quickly and more accurately.

By interfacing with our FBO provider tables, the system would then plot the locations within 1/10th of their trip duration.
