• Process owner for high volume GFNV battery pack assembly line. Processes include part installation, fastening, vision, leak testing, electrical testing and dispense.• Rebalanced multi station processes to integrate hardware and software for fastening tool positioning system to improve ergonomics, reduce quality escapes, and improve cycle time. • Optimized and setup manufacturing controls such as final angle, torque rate and torque rate deviation on fastening programs to improve yield by 40% and product quality (torque residuals).• Resolved product non-conformances, investigated root causes and implemented corrective actions to improve yield by up to 40-50%.• Cross functional lead for first pass yield. Drove action items and led yield improvement projects to increase overall line fpy by 4.5%. • Developed and launched new manufacturing processes (vision & fastening systems) for new products under short notice and tight timelines. • Created an automated data reporting app to provide live production critical key performance indicators on an hourly basis.• Improved issue detection and reduced tear down costs through automated python scripts utilizing API calls and sql.

- Created comprehensive, end-to-end process characterization cascades to evaluate the impact of critical to quality attributes on 10 different manufacturing processes. - Prepared recommendations and improvements in process controls resulting in the reduction of finished good testing and a cost savings of $500k per year. - Designed and led supplier corrective action strategy to reduce risk for incoming raw material quality- Authored DOE protocol to test feasibility of manufacturing processes for a new product development project. Traveled to Puerto Rico manufacturing site to execute completion of the protocol. Documented results through a completion report.- Led collaboration with cross functional teams to decommission and obsolete low gross profit products. This included inventory destruction, equipment disposition, and supplier disengagement. Revamped the franchise procedure to align all future decommissioning projects. - Led the execution of validation activities to launch one new product code. Managed the design change documentation for other new product codes. - Coordinated multiple inter-department events to raise over $10,000 for Operation Smile, United Way and JnJ Credo.
