Projects

Spotify Wrapped Programming Project

I am a big music fan, and a daily user of the music streaming program Spotify. For years I have enjoyed Spotify’s annual ‘Spotify Wrapped’ year-end summary of my most listened to artists, but I have always suspected that the songs and artists that Spotify showed as my most listened did not line up with my actual listening habits.

I decided to test this by taking on a small programming project where I created a Python script that would go through an individual’s Spotify data and provide a user with their true listening stats.

I was able to prove that there are indeed some differences between what Spotify shows us, and our actual most listened to songs and artists. My code and all my program iterations can be found on my GitHub page, here.

McMaster NEUDOSE - CubeSat Structural Design

From May 2020 to August 2022, I was a Structural Specialist for the NEUDOSE CubeSat mission at McMaster University. The NEUDOSE CubeSat is a satellite being designed and built at McMaster University as part of CSA’s CCP initiative (learn more about the project here).

As part of the team, I have worked on the following items:

Selection and design of structural fastening mechanisms
Generation of BOMs for structural components of satellite
Structural calculations of failure modes and design specifications
Detailed mechanical GD&T for manufacture of structural components

Emission Reduction in Residential Buildings - Engineering & Society Capstone Project

As part of my final year Engineering & Society Capstone course, I worked with a group of 3 other students to develop a high-level design to reduce carbon emissions in Multi-Unit Residential Buildings (MURBs) in Toronto.

The goal of this project was to develop a high-level design at the unit level which could reduce carbon emissions made by MURBs in Toronto. My primary responsibilities included completing technical performance assessment and economic assessments of design alternatives, generating performance predictions (based off published data), and drafting a detailed report for our client.

As a group we were able to develop a design that could achieve up to 20% energy savings with a payback under 4 years.

Net-Zero Energy Retrofit Design for Community Building in Burlington, ON

As part of my Sustainable Energy Systems course, I worked on a energy retrofit design for a community building in Burlington, Ontario.

Far this project, I used the energy assessment tool RetScreen to model the energy use of the building, and design a retrofit that would achieve net-zero. With a significant utility update involving a heat pump system (to replace old furnaces), added insulation, improved appliacnes and added solar panels I was able to achieve a net-zero energy solution for the building with a payback of 8.5 years.

Dropper-Post Design

As part of my Mechanical Design Engineering course I worked with a group of 4 other students to design a mountain bike dropper post. A dropper post is a type of seat post that is rapidly adjustable for mountain bikes.

Squat Rack Safety Bars

As a personal project, I worked on a design for safety bars for a squat rack. I decided to design these when I realized the squat rack I purchased during the pandemic came without them, and I wanted to ensure I was lifting safely.

To design these I completed structural calculations for all welds and bending of the beam under extreme loading conditions.
