Jeff Sepeta

Senior IT Consultant

Professional Summary:

IT Veteran with 35 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 health care 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.
