• Lead a global purchasing team in stampings, plastic, and powder metals to develop a global strategy for each commodity, Total Spend coverage 130M Annually. Work to manage the objective cost, schedule, and performance of the sourced platform. o Cost Objective – Track all sourcing performance to zero delta relative to program Operating Income o Schedule -- Work with AQE to assure supplier is meeting launch gates and mitigate as required by program timing o Performance -- Assure zero Piece Price impact and leverage new business to enhance current program performance. • Lead Design to Cost analysis with engineering and work with suppliers to provide innovative ways to take cost out of product and process, and enhance overall program performance • Leverage relationships and new business to lower cost on existing programs, and ultimately enhance Operating Income of the post Start Of Production (SOP) programs. • Align with PLPM on out year (2022 – 2025) pricing and technology needs… o Manage projects for Design to Cost projects to identify 2022 – 2025 road map for commercial and engineering specific actions/owner to achieve pricing objectives o Manage cross regional/functional teams to align commercial and technical supplier needs, and identify and develop disruptive suppliers to meet our 2022 – 2025 objectives o Align resources from Quality, Engineering, and Commodity teams to assure quick and efficient onboarding of new suppliers. Note: As a result of the above, under my leadership, my team has been able to reduce price points for following parts Rotor - 27% Worm Gear - 19% Pully - 23% Which allowed us to meet or exceed our 2022 expectations

• Support a global purchasing team in stampings, powder metals, plastics, and rubber. • Develop product costs working with global Nexteer/supplier plants and conduct further opportunity analysis of complex bill of materials. • Created training materials on costing for Global Sales Team. • Organize and conduct global Training sessions on Cost drivers, Cost Modeling, and Negotiations to allow for purchasing organization to better understand supplier Quotations and source future product at Best Cost Upfront. • Managed Mentoring program for Global Buyer Team. • Managed Training Schedules for global Global Sales Team. • Lead Business Case Impact Studies within team and formally reported out the final savings potential to upper Management. • Analyzed over $100M in spend, identified $15M in savings, helped to negotiated $3.5M in savings. • Conduct commercial cost sensitivity studies, financial modeling and risk assessment. • Provide technical input through cost analysis tools to refine and improve commodity strategies, creating fact-based negotiations and assisting in decision making.

• Lead a global team of cost engineers in stampings, hot forgings, powder metals, tubes, and assemblies. • Develop product costs working with global TRW/supplier plants and conduct further opportunity analysis of complex bill of materials. • Conduct commercial cost sensitivity studies, financial modeling, and risk assessment. • Conduct supplier cost audits and supplier health assessment to support business units and support supplier cost audits. • Support the supplier negotiation process (part of McKinsey value capture activity). • Communicate commodity spend analytics and strategies to senior management.

• One of original 3 team members to start the Cost Engineering group at TRW. • Worked as the Lead Global Cost Engineer for stampings commodity and worked with suppliers to understand their cost structure through phone and plant visits. • During first year in Cost engineering role, analyzed $74M in spend, identified $9M in savings, helped to negotiated $2M in savings and avoid $1M in supplier requested steel increases. • Development of a Global Cost Tool Standard for stampings to improve speed and accuracy in the bid proposal phase and helped commodity managers to implement cost targets with this tool. • Analyzed new designs for any possible cost savings. • Maintained database of current and archived cost models for data collection and cost predictor purposes. • Maintained communication with global stamping companies to ensure cost model compatibility and worked with commodity to help them challenge suppliers on their pricing based upon past data collected. • Lead weekly meetings to discuss current ongoing projects. • Hired and trained new cost engineers as they joined the team. • Previously supported PCB, sensors, and wire harness commodities. • Worked with VA/VE group to understand and develop standard pricing of PCBs

• One of two engineers that performed worst case analysis of all approved circuits. Circuit libraries were written to track the information and calculations gathered during the design and analysis phase. • Lead a Six Sigma Green Belt project to ensure usage of the above circuit libraries containing design documentation, description schematics, and MathCAD analysis for use globally to eliminate design proliferation. • Lead electrical design engineer for the advanced product development core group for EBC450 brake system electronic control units (ECU). After design was robust, transferred to the applications group for individual customers. Also supported preceding EBC440 core activities working as a design engineer. • Responsible for making sure the software and the hardware groups fully understood the content in new designs. • Designed and tested very tightly packed circuit boards. Design work includes high and low side driver circuits, Discrete I/Os, Microprocessor and ASIC support circuits, CAN, and Class 2 (J1850) communication circuits. Responsible for hardware testing including bench, failsafe, description, schematics, and MathCAD analysis. • Managed an open issues list to organize group efforts and attended weekly meeting with TRW global design team and suppliers to track changes and issues. • Worked with ECU suppliers to ensure proper design, pricing, and timing.

• Lead electrical design engineer for Control Actuation Systems (CAS) team. Actuator control includes the position feedback loop which contained Hall-Effect sensors (motor position) and Arc-Segment feedback potentiometers (output shaft position). • Designed and tested a very tightly packed 3-axis controller for a 2.75-inch missile. The design includes a H-Bridge switching power electronics to control the actuators’ brushless DC motors. • Oversaw detailed design of a complex multi-layer flex circuit which was new for our team’s design. • Responsible for the hardware and software testing and defined the interfaces to other subsystems. • Testing included evaluation of both the Actuator Electronics Unit (AEU) and actuator hardware, which together comprise the CAS. The functionality of the AEU was verified by monitoring the interrupt signals went between the microcontroller and peripherals, as well as the Pulse-Width-Modulations (PW and direction signals generated to control the amplifier for the actuator hardware.
