• Created 2D and 3D drawings in SolidWorks and NX for design validation and manufacturing. • Built prototypes utilizing machining, sheet metal, and 3D printing to support fast-changing battery research needs. • Managed and communicated with vendors to outsource parts precisely and ensure on-time delivery. • Redesigned substrate holder for vacuum deposition chamber in collaboration with process team, integrating heating element with copper holder that improved substrate heating/cooling efficiency by at least 30%. • Designed airtight sample enclosure for XRD equipment with material characterization team to protect air-sensitive battery samples and develop experimental in-situ characterization method. • Led and designed pressure measurement tests for battery cells and analyzed data to filter out drift in force sensors, contributing to understanding of volume change in battery material during cycling in research process. • Held technical meetings in Mandarin with vendors in China for customized equipment acquiring.

• Led the mechanical design of a sentry robot that competed in RoboMaster battle bot competition annually. • Revised the attachment system of the sentry robot that hangs and runs on a rail to improve stability and minimize the effect of inertia when the robot stops and shoots. • Integrated a lazy Susan bearing into the yaw motor assembly to evenly distribute axial loads. • Designed a feeding mechanism for the robot’s firing system that loads ammos from the side of the barrel, separating the ammo hopper from pitching movement of the auto-targeting barrel, reducing loads on the pitch motor and increasing the accuracy of shooting. • Designed the chassis panel of the sentry robot in collaboration with the EE team to accommodate electrical components and ensure minimum compromises to the movement of the robot. • Designed parts in SolidWorks for machining and 3D printing, and worked with complex assembly models to simulate and validate design concepts.

• Greeted and guided customers, assisted customer with inquiries, followed procedures for safe food preparation, handled monetary transactions, kept the serving section clean and well-stocked, and operated the commercial dishwasher. • Obtained skills in maintaining good customer service, multitasking, efficient communication and team-working in a dynamic environment.
