Manage John Deere Kernersville's returnable program. Project management in the $1M+ range. Build business cases backed by ROI through waste reduction, truck cubing, parts cost reduction, etc. Optimize use of John Deere Worldwide Logistics bulk containers and bins (Orbis). Developed container calculator to compare a part against different containers to optimize based on volume, production demand, order quantity, safety stock, etc. Implementation of modular rack design for extended savings for years to come. Lineside support (process/product engineer) during DEX builds.

Develop returnables for new model releases, improving sustainability.

• Tsukuba Returnables ($700K over 2 years, 2022 to 2023) will yield a $3M return in 4 years.
• 510 Returnables ($225K, 1 year, 2023), $1M return in 5 years.
• DEX Returnables ($17.5M over 5 years, 2022 to 2027) found ways to reduce the budget to $13.5M.

Refer to Manufacturing Engineer role. Was promoted to Engineer after 7 months in role.

Review all warranty claims submitted on 13-47 metric ton excavators.

• Created 4 Power BI dashboards, innovating warranty tracking and saving time. Dashboards focused on warranty recovery, midsize excavator quality, 470 excavator quality, and warranty cost flow.
• Recipient of a 2021 Project Excellence Award for 470 Quality/Hydraulic Leak Reduction. Contributed to two project teams, reducing warranty by 50% and cutting hydraulic leak claims by 50% on all models produced in Kernersville.

• Reviewed defects with technicians and trained them on assembly processes.
• Evaluated stations for operational method sheet improvements, both process and design related.
• Submitted over 50 design and process change requests and maintained a 90% acceptance rate.
• Supported assembly engineering through line design changes. Identifying issues and resolutions.
