Jeff Sepeta


Professional Summary:

IT Veteran with 30 years of experience across a wide range of technical disciplines and pragmatic business practices.

  • I can explain complex technical subjects in an engaging and clearly understood manner to non-technical staff. Change happens exponentially, yet not all trends bring value. I only recommend technologies and processes with a proven, successful track record.
  • I have worked in the manufacturing, distribution, legal, marketing, and medical industries. I focus on finding the best ways to implement technologies and processes which improve workflow and reduce quality-control issues to enhance customers’ experiences. Sustained business growth requires customer satisfaction.
  • Example: Utilizing business process discovery, analysis, and mapping led to recovering $180,000 in lost annual revenue due to a poorly implemented ERP which failed to charge adequately for oversized shipping. This required coordinating the efforts of 3 independent coding teams located in different states, reporting to different bosses.
