About

Design that is built to be built

I am a Mechanical Engineer with more than ten years of experience in industrial product development, manufacturing improvement and engineering leadership within the polymer film manufacturing industry.

I work across mechanical design, product validation and design for manufacturing, and I collaborate closely with design, production, quality and management teams so that a concept moves smoothly from the first sketch to the shop floor.
