Research Assistant

University of Waterloo | Waterloo, ON

Jan 2023 - Present

Currently, I am an undergraduate research assistant, supervised by Dr. Ramahi.

Circuit Design Hardware Engineering Intern

Untether AI | Toronto, ON

Sep - Dec 2023

Working at Untether AI exposed me to the silicon industry and digital design. I was on the circuit design team and worked on Cadence models to calculate propagation delays and setup/hold times. I also created Python scripts to calculate the static and idle power consumption across the chip.

PoweRFul Meter

Waterloo, ON

May 2022 - Mar 2023

Myself and 5 others built what we call a "PoweRFul Meter" for our fourth-year design project. This device is a hand-held device that can measure the power of signals across the spectrum 2.375 GHz to 2.525 GHz. A cool feature we added it to be calculate the EIRP of the transmitter by adding a LiDAR sensor to obtain the distance and estimate the path loss, according to the Friis equation. The main application of the PoweRFul Meter is to measure wifi-signal strength, which is very helpful to IoT designers and troubleshooting in large office spaces.

My role was the design of the power-detector circuit and developing the firmware of the device. The firmware consists of an ADC to sample the output of the power detector, communicating with an oscillator with SPI, and communicating with the LiDAR sensor with I2C. The source code can be viewed on my Github repo.

We completed and presented our project at a Symposium on March 15, 2023. You can view more project details further down this page in the Projects section.

UW Orbital Design Team: Communications Subtean Member

Waterloo, ON

Jan - May 2022

UW Orbital is a design team at the University of Waterloo that is trying to design and launch a CubeSat satellite into space for the Canadian Satelite Design Challenge (CSDC). I was apart of the fullstack development team and worked on the frontend and backend of a Mission Control Centre app which would be used as an interface to send and receive data from the satellite. I used React for the frontend and Flask and MySQL for the backend.
