HIGHLIGHTED ACCOMPLISHMENTS
Managed the parts lists and the tracking of the progress of ten designers, to ensure that the required milestone was reached on time. During the most critical period, I was able to achieve a reduction of 25 in the number of remaining unreleased drawings, during a period of four days.
Determined why customers were returning products and recommended improvements to reduce the return rates.
Worked on development of new products, including gear train, grease gun and ammunition feed.
Tested products to determine if they met customer or regulatory requirements.
Designed and built test equipment to evaluate and compare proposed product designs, and to select optimal designs to manufacture and sell.
Developed thermal models to evaluate proposed designs for electronics and determined whether they would be likely to overheat.
Selected materials to reduce cost or improve thermal performance.
INDUSTRIES
Defense/aerospace
Electronics
Automotive
Power tools
