WORK HISTORY
Sr Mechanical Design Engineer @Caterpillar Inc.
Tucson, AZ, US
Lead mechanical design for the NPI Program - Dynamic Energy Transfer (DET), producing GD & T complaint drawings and managing documentation via Teamcenter. Integrated precision mechanical components into design ensuring high performance and reliability.• Engineered patent-pending Modular Boom Enclosure system to enable scalable system integration and improved field serviceability. Led design and peer review processes to drive continuous improvement and enhance system reliability and performance. • Achieved a 25% improvement in assembly and serviceability time through modular design and DFM/DFA principles.• Facilitated cross-functional DFMEA for the Dynamic Energy Transfer System, reducing potential failure modes from 14 to 1 and accelerating program timelines by 3 weeks.• Supported cross-functional collaboration through all phases of the product development lifecycle from concept and prototyping to verification, manufacturing transfer. • Executed bolted joint analysis using Creo Simulate to validate structural integrity and system durability under multiple load and fatigue conditions.
