Summary:
Relevant engineering background includes assignments dealing with new product design from cradle to grave using the NPI tollgate method, BOMs, production launch, cost optimization, purchasing, capital expenditures, project planning, prototyping, testing, implementation, OEM, and supplier technical support, problem resolution plus extensive documentation skills gained through technical report writing and presentation.
Interface concurrently with Quality, Production, BOMs/Specs, Design Groups, Materials, Engineering, Suppliers, and OEMs to resolve production-related issues to meet shipping dates.
Use AutoCAD & SolidWorks to bring all the pieces together in thorough and complete documentation packages. Some of my assignments have also required Pro/Engineer.
Use Excel & Minitab along with CAD & FEA software to provide engineering calculations to verify and optimize design intent and review proving analytically the results in advance to make the best use of time and dollars in testing (prototype, alpha, beta) and launch (pilot and production).
