Served as a core engineer for the DeWALT Powershift 10ah battery program. My work included mechanical improvements on high-impact concrete tools like rammers, plate compactors, and vibrators.
My responsibilities centered on electromechanical design, covering everything from PCB modifications and cell-level analysis to comprehensive safety, reliability, and performance testing.
I led the design of a next-generation job site blower, achieving:
From brainstorming to production, I managed the project, using CFD simulations to optimize the axial fan and performing tolerance stack-ups and structural analysis to ensure robustness.
The market-leading aluminum track saw guide was prone to damage during shipping and use. I redesigned the track to enhance durability without sacrificing precision.
This project required extensive tolerance analysis, FEA, and reliability testing to meet demanding performance and durability targets.
As part of the speaker design team, I used FEA to optimize the woofer spider's deformation behavior for sound quality and longevity. I also ran CFD simulations on speaker ports to enhance acoustic efficiency by analyzing airflow and pressure.
I contributed to the mechanical design of an audio system's light pipe to ensure optimal illumination. My work involved:
In addition to the projects above, I designed a new housing for a grinder and conducted extensive testing on a wide range of DEWALT tools, including drills, impacts, grinders, and various saws.
