Professional Experience
HEWLETT-PACKARD CO., San Diego, California 1994 – present
SeniorSystems Integrationand Mechanical DesignEngineer
2 years developing HP’s MultiJet Fusion Technology. Involved in digging deep intounderstanding the
science of fusingandmanagingmultiplecomplexsystemsinordertooptimize fusingperformance. I’ve
also developed powerful data visualization tools in Python that are in use across HP today.
2 years developing an FDMsystem prototype. Focused on system interactions and optimizationsfor
generating parts with strength and accuracy at unprecedented speed.
19 years developing scanning hardware and system solutions for All-in-One/MFP inkjet and Laserjet
print/copy/scan products. Productsrangedfromthe verylowend($49) tothe veryhighend($4,000+),
providingabroadarrayof experience withdifferentfocuspoints. Atthe low end,the focuswasonhigh
volume and low cost, while at the high end the focus was on performance and durability.
While initially concentrated on mechanical product design, in the last 12 years focus shifted towards
complete systemandproductintegrationwhichrequiresarange of additional,importantskills beyond
those of the typical mechanical design engineer:
 Program management and leadership, pulling together team members from all aspects of
product development including mechanical, electrical, firmware, software, manufacturing,
testing, reliability, and regulatory engineers. This includes integrating teams from a range of
geographies to deliver a product solution.
 Team leadership - driving coordination meetings, development schedules, budget planning,
build planning and coordination, issue tracking, defect resolution and tracking.
 Highly adept at multiple methodsof development. From the in-house approach which allows
tight integration of components to the Force Multiplier approach, where leadership and
direction of other partners is used to develop solutions.
