These are some of the projects I've led or substantially contributed to in work, school, or independent studies. This portfolio isn't exhaustive, but rather a representative sample of the type of work I enjoy doing.
A Helping Hand - The Surgical Assistant
September 2020 - Present
In a group of 4, I am developing an AI-driven system to automate tool delivery to the surgeon within an operating room during knee arthroplasty. The system consists of 5 stages: tool detection, gripping, translation, orientation, and hand-off. We are collaborating with the University of Waterloo RoboHub research facility to validate our design.

Prototyping Course Creation
June 2020 - August 2020
The University of Waterloo Systems Design Engineering Department sought to offer a new workshop-based course acquainting students with the fundamentals of technical design and prototyping. I was hired to develop the course syllabus based on my understanding of gaps in practical knowledge in the curriculum and useful skills in industry. Additionally, I also introduced video content, experiments, and projects to guide the instructional team with remote delivery of the course.

Maze-Solving Stewart Platform
January 2020 - April 2020
In a group of 5, I designed, built, and programmed a 6-DOF parallel actuation platform to solve mazes. The device was able to take an input from a joystick to solve the maze, save the commands, and play them back for repeated solving.

Verification of Smart Antenna Systems
January 2020 - March 2020
I was an Undergraduate Research Assistant with the Centre for Intelligent Antenna and Radio Systems (CIARS) at the University of Waterloo. I developed and implemented automated testing procedures for new radar technology. I wrote python scripts for precision motion stages, designed and assembled custom test fixtures, and acquired data for Synthetic Aperture Radar (SAR) verification.

Wearable UV Sensor Development + Manufacturing
May 2018 - August 2018
I made improvements to the existing Suncayr Inc. product, the SPOT™, for large scale production, including optimizing device reusability, rectifying compatibility issues with certain sunscreens, and reducing manufacturing costs by investigating alternative materials.
I worked with contract manufacturers to deliver Suncayr's first successful production run with 300 000+ units of the Minimum Viable Product. The units I helped make are currently being used by consumers.

Material Selection for Aluminium Bike Frame
February 2018- March 2018
I determined the ideal material composition and heat treatment schedule for an Aluminium mountain bike frame from functional requirements and criteria including low cost, high strength, and low weight. My final selection was Al 6061 with a solution treatment, quenching, and aging process.

Portable Oxygen Concentrator Prototype
September 2017 - December 2017
I designed, built, and programmed a portable oxygen concentrator prototype for VivaSpire Inc to serve as both a working prototype of their flagship product, as well as to run automated tests on device performance and efficiency. It was capable of running the equivalent of 3 portable oxygen concentrators simultaneously, which is why it is larger than what would eventually be adopted into the final product. I designed all of the electrical and mechanical subsystems myself, and wrote the code collaboratively with my supervisor. My design produced 10x more oxygen than the previous proof-of-concept.

Autonomous Gardening Assistant Robot
May 2017- August 2017
In a group of 4, I designed, built, programmed, and tested an autonomous robot that aimed to assist individuals with the laborious aspects of gardening. The robot was able to follow a line placed on the ground and stop to dig holes in dirt where the user placed coloured tape. I programmed the robot in RobotC, integrated all sensors and motors, and validated the design. Employed rapid prototyping (3D printing, laser cutting) to fabricate subsystems.
