 Was instrumental to the re-design, development and deployment of HCS (Hardware Control
Software). HCS forms the core functionality for automation control in Newport’s products, and
is deployed as an AddIn to the Integra framework.
 Was instrumental to the design and development of several prototype automation systems
that were completed on time for, and displayed at, OFC - Optical Fiber Communication 2002
Conference in Anaheim, CA.
 Designed and developed the custom operator interface for a first of its kind top secret
machine for W. L. Gore. After development, I was sent to Delaware for deployment and final
acceptance. This machine is still in production with no tech support calls.
 Designed and developed special versions of Integra and HCS for deployment on low-res
(640x480) flat screen monitors as required by Seagate for a full systems upgrade of their
