I am a driven mechanical engineer with a passion for product development and a knack for mechanical design. I like to apply mechanical engineering principles with creative thinking to create reliable and elegant solutions.

From my first business of repairing snowboards to my more recent endeavours with Valley Prototyping Solutions Inc., my entrepreneurial spirit has led me to solving interesting problems and picking up new skills on the go.

If you're interested in seeing some of the projects I have been a part of, have a look through my portfolio below and feel free to send me a message.

Thanks,

Education

University of Manitoba

Bachelor of Science - Mechanical Engineering Co-op/IIP Option

Graduation: May 2020

I developed my passion for mechanical engineering, found invaluable mentorship, and gained useful skills through courses like Engineering Design, Advanced Graphical Communications (GD&T), Machine Design, and Design of Biomechanical Devices.

Engineering Design Capstone Project

My team designed a mechanism for Vidir Vertical Storage Solutions to load 2,500 lbs. products into their storage carousels. We built and tested a prototype to validate our design.

Machine Design Final Project

Our team designed a powertrain that uses planetary gears to safely transmit power in the UMSAE Baja vehicle. We created a 3:5 scale model using FDM 3D printing.

Advanced Graphical Communications (GD&T)

I learned how to apply practical tolerances to a design and became proficient in communicating design intent using Geometric Dimensioning and Tolerancing (GD&T).

Analysis of Composite and Multifunctional Material

I learned about stress and strain in composite and multifunctional materials such as carbon-fibre reinforced polymers (CFRP). Topics included anisotropic elasticity, failure criterion, and design philosophies. For my final project, my team designed an 8-ply carbon-fibre shaft, and I used ANSYS to conduct finite element analysis (FEA).

Managing Partner

January 2021 - Present

After collaborating on projects for several years, I joined Shea Hunt as Managing Partner at Valley Prototyping Solutions. I really enjoy what this role allows me to do; I create affordable, functional prototypes for our clients using our own equipment, local fabrication shops, and online marketplaces for custom manufacturing. Unfortunately, I am unable to share photos of several projects that involved design, photorealistic rendering, and prototyping in the agriculture and consumer electronics industries.

Design and Fabrication of 3D Printed Microscope Mount

Designed and fabricated a highly adjustable 3D printed microscope mount used for imaging the entire surface of amphibian embryos. Nine microscopes are arrayed in a spherical formation around an imaging stage to create whole surface images of objects anywhere from 0.5 mm^3 to 60 mm^3 in size.

Mechanical Engineering Lead

August 2022 - May 2024

Design & Production of V0.5 FeedFlo Sensor

After being contracted by FeedFlo on a couple of projects, I joined full-time to lead the mechanical re-design and ramp up manufacturing of their feed measurement sensor.

FeedFlo Wins Startup TNT Summit VIII

After presenting at the Top 20 and Top 5 Finale, FeedFlo was announced as winner of the Startup TNT Summit VIII Manitoba Division in November 2023.

R-Tech Industries Ltd.

General Manager and Managing Engineer, EIT

May 2020 - April 2022

My role involved overseeing the day-to-day operations of the organization ensuring successful operation and continuous improvement by taking the lead on:
• Developing project management, customer relationship management, and inventory management systems
• Coordinating team meetings and product development sessions
• Planning several facility renovations
• Providing sales and technical support to customers
• Developing operator’s manuals for new products
• Launching a new website and social media channels
• Implementing a serial number system for tracking equipment
• Managing accounts and allocating capital effectively

On the Engineering side, I worked with customers to define their custom equipment specifications, set pricing, designed a solution in CAD, sourced materials, and oversaw the fabrication for projects that may be viewed below.

Managing Owner

October 2017 - December 2020

While I was a student, I operated a sole proprietorship that helped other entrepreneurs and hobbyists. I sold and serviced 3D printers, and provided services such as computer-aided-design, 3D printing, and CNC woodworking.

Custom Design & 3D Printing

I designed custom parts in SolidWorks and Fusion 360, and 3D printed end-use parts for clients.

CNC Woodworking

Selling and Servicing 3D Printers

I sold 3D printers to customers across the world using eBay, Amazon, and my own Shopify e-commerce store. I also offered servicing of 3D printers - diagnosing issues and resolving them for customers.

Winnipeg Fighting COVID

Director and Volunteer Coordinator

March 2020 - March 2021

Winnipeg Fighting COVID is a non-profit corporation founded in March of 2020. Over 100 volunteers came together to use 3D printing to help our front-line workers. Together, we organized, standardized, sanitized, and distributed over nineteen thousand “ear-savers” to front-line workers across Manitoba at no cost to them. I volunteered as one of four directors and as the volunteer coordinator. I helped with recruiting volunteers and sending regular updates, 3D printing, and organizing/making deliveries to front-line workers.

Research Intern

May 2019 - August 2019

I spent the summer in Southern Germany as a Research Intern working on a primary research project as well as several smaller projects related to mechanical engineering.

Design of Powered Upper Body Exoskeleton

Working closely with other mechanical engineering students, I designed and built the electrical system for a 3D printed powered upper body exoskeleton, and programmed the controls in Arduino IDE to operate via joystick and myoelectric sensors attached to the user. I modelled and 3D printed the enclosures for the microcontroller and joystick, with emergency stops integrated into each.

Mechanical Engineering Intern

May 2018 - August 2018

I worked on the development of a radio frequency strain gauge for rail, working hands-on fabricating and assembling prototypes of electromechanical devices. I used SOLIDWORKS to design new parts and modify existing designs to tailor to the customers' requirements, and create engineering drawings for fabrication and inspection purposes.

Production Engineering Intern and Maintenance Engineering Intern

May 2017 - December 2017

I applied principles of Lean Six Sigma to improve operations, and improved machine reliability using 6S principles and failure mode and effects analyses. I conducted cost-benefit analyses, and led cost-saving projects in the manufacturing facility. I prepared drawings of a proposed floor plan for renovations in the manufacturing facility, and helped to oversee the renovations.

Development and Implementation of a Dewpoint Monitoring System

In order to reduce natural gas usage, I implemented a system to automatically adjust the heat of the beverage can warming machine based on the dewpoint temperature in the warehouse. This ensures that the cans are heated to the dewpoint temperature prior to storage in order to prevent condensation, but not unnecessarily overheated. My co-worker and I developed the system using empirical data and thorough validation.

Personal Projects
