Biography

Experienced engineer across many different industries :  mobile application development, interactive digital television, passive sonar, condition monitoring for heavy industry, remote services, access control / intrusion detection, and automated optical inspection.

Responsible for the planning, design, development, and execution of complex engineering projects within startups and large corporate environments.  Created product road maps by working with customers, senior management, and market analysts. Performed voice-of-the-customer activities to uncover and validate assumptions about product worth.

Process-oriented and experienced in setting up, monitoring, and modifying engineering processes for the successful delivery of products.  Worked with ISO-9000, UTC's ACE, and CMMI process systems. Taught academic and commercial courses in why processes are important, and when they are not.

Works as a consultant on intellectual property litigation performing source code review, documentation assessment, and preparation of testifying expert reports.

Joined  CT State Community College at Middlesex campus in 2022 teaching computer science and engineering courses.
