Automation Systems Engineer and Project Manager with wide array of experience in multiple industries, including aerospace, chemical processing, packaging, material handling, and heat treating. Skilled in machine and process design, controls design and programming, installation, support, documentation, and training for various levels of personnel.I have a passion for solving complex manufacturing problems and helping companies improve the bottom line, by delivering on key performance metrics such as machine availability, operational efficiency, and process reliability and repeatability. By understanding the needs of the process, and designing systems to compensate for variability in operations caused by environmental factors, and human induced errors, such as incomplete maintenance, or inadequate operator ability, the systems I’ve developed have been successful in reducing scrap and saving on operational costs, while enhancing product quality and driving increased profits.
