ENGINEERING
PORTFOLIO
This project was inspired by my hobby of playing casual poker games with friends. I find that combining engineering with my personal interests is the best way to build motivation throughout the projects journey.
This machine has 3 built in programs which can be accessed by the user through the control panel.
The first program will create different sized starting stacks for each player based on the users input.
The second program will count the dollar value of a players chip stack based on the dollar weight of each different coloured chip.
The third program will clean up the finished poker game by organizing all of the chips into columns of their respected colours.

Cardboard Box Assembly Line
During my first mechatronics project at Humber College I helped lead my team in designing, manufacturing, and presenting a fully functional assembly line that closes a 2 cubic inch cardboard box. In completion of this project we used a pneumatic cylinder with a vacuum suction cup to pull the box into position where it is struck with compressed air from multiple directions. These three streams of air, along with a servo motor are used to close all three lids of the box. A second pneumatic cylinder with a plunger is then used to push the closed box off of the assembly line, allowing the entire process to start again.

Spinaline®
Designed for
My final capstone project at George Brown College was a team assignment that involved us choosing a client in which we had to design and build a prototype of a product they've envisioned. Our final prototype was a fully functional spinal alignment system that fits on top of any existing seat. We accomplished this challenge by using 3 separate inflatable air bladders to press against the users spine in their desired location.

LIME SLICER
Designed for
By NELK
This lime slicer is one of the products I designed intended to be manufactured through injection molding. The final product includes 3 separate parts that are detachable for storage and cleaning, and it showcases an ergonomic handle designed for comfort and strength. Its 4 interlocking blades offer the most effective way to cut 8 equally sized lime wedges.

PUBLIC TRANSIT POLE CLAMP
Designed for

Working as a freelance product developer I was given the challenge to design a custom clamp that can be used on public transit. The client wanted a product that will allow the user to firmly hold onto a public transit pole without having to physically touch the pole itself. This device will help prevent the spread of Covid-19 and allow the user to feel more safe with public travel.
