• Worked on a 3D Touch fixture audit tool design• Led hardware design on a concept for modular fixture audit platform• Audit platform design was highly cross functional with significant mechanical constraints, and included custom IC integration • Selected as speech finalist to present the platform design concept to upper management

• Designed high speed, 4-layer, PCB to drive LCD and LCD backlight• Measured clock amplitude and rise/fall time, and jitter for using MCU as clock buffer• Configured sensors over I2C using AARDVARK, and created sensor test procedures before handoff to firmware team• Selected high speed (up to 5MHz), low power, compact, low resolution ADC for voltage sampling• Hardware bringup of next-generation consumer electronic product

Santa Clara, California, Us

• Designed two fabric cards to test functionality of network switch chassis midplanes• Took ownership of fabric cards through fab stage and bringup, communicating with multiple teams and PCB fab• Performed HyperLynx power plane simulation to determine optimal component placement for minimal voltage drop• Compared potential power burner solutions based on maximum junction temperature, thermal conductivity and package• Measured voltage ripple caused by high power fans in order to determine if further filtering was required• Validated fan power connectors in temperature chambers, and met with vendors to discuss the results• Configured JTAG boundary scan using Corelis ScanExpress for in-lab testing of network switch line card

Santa Clara, California, Us

• Created a system for caching server state in Python to reduce start time of repeated tests • Created a program to account for known bugs during chassis and board bringup• Improved usability of Arista’s manufacturing website for use by Manufacturing and Engineering teams

Waterloo, Ontario, Ca

• Wired controller area network (CAN) between BeagleBones and other boards• Troubleshot CAN driver issues, one of which involved message IDs being bit-shifted • Maintained test setup hardware on which a model car drove autonomously

Waterloo, On, Ca

• Performed root cause analysis on approximately 50 packet processor circuit board failures• Monitored, ran, debugged and maintained pilot runs on several server systems• Gained rework experience replacing components during debug• Produced an instructional booklet directed at new hires, that was incorporated as a controlled document in the company

Victoria, Bc, Ca

• Researched and gained knowledge in medical device standards to ensure designs met FDA requirements• Responsible for lab organization and station checks to ensure lab integrity• Worked with senior engineers to build prototypes of medical equipment

Victoria, Bc, Ca

• Carried out manufacturing of small batches of medical devices in groups, and alone, developing strong communication skills and technical knowledge of devices.• Followed manufacturing procedures, developing an understanding of the way in which they are written and how to most efficiently carry out tasks.• Maintained a clean work environment, cleaned work areas and organized tools when necessary
