On the Data Engine team at Embark I built and designed tools to facilitate and accelerate deep learning workflows such as data labeling, dataset curation, and metrics evaluation. I worked closely with deep learning researchers and data quality teams for feedback and improvement of tools that they use on a daily basis.

At Miovision on the Computer Vision (CV) team, I worked on products and tooling that support CV and ML development: data pipelines, analytics tools, experiment tracking, and infrastructure. Primarily, I was an owner for our computer vision configuration library which customers use to configure traffic scenes for CV: eg. camera pose, scene location+scale, scene geometry, regions of interest, desired outputs. In addition, I dabbled in some classical CV algorithm development for identifying vehicle movements.

As a co-op student at Miovision I worked as a software developer on the computer vision team, experimenting with methods of improving our traffic video detection product and improving systems supporting ML training. - Integrated MLflow into TensorFlow model training to track deep learning experiments and production training - Researched and prototyped template matching algorithms for vehicle movement identification in Python - Investigated vehicle classification methods for interpreting predictions from frames in video using Python and C++

At Swift Labs (now acquired by Blackline Safety), I worked on the firmware team on their flexible hardware platform product. - Developed GPS library to manage asynchronous location updates for IoT tracker using C, ZephyrOS, and Nordic SDK - Proposed new event-driven embedded software architecture and collaborated with team to finalize and implement - Wrote drivers for ambient light sensor, temperature sensor, fuel gauge, and charger ICs using C, ZephyrOS, and I2C protocol - Worked closely with sales as a subject matter expert on customer calls

At AvidBots I worked on the robot systems software team, developing C++ application software leveraging ROS to control an autonomous floor-cleaning robot. - Eliminated blindspot from dynamic robot safety zone using Graham’s scan algorithm in C++ - Troubleshooted and refactored drive commands to correct for erratic motor controller behaviour on new hardware - Added front camera display to assist with manual robot operation using Electron and ROS - Developed robot health monitor features for verifying integrity of robot functionality by monitoring completion of robot commandsFrom manager:"Jeff has demonstrated superior abilities in everything he was asked to do, and his work was always beyond expectations in terms of quality, quantity and speed. He has often demonstrated initiative toward and beyond his job description.""Outstanding work, demonstrated depth and breadth of knowledge and behaviour more typical of experienced engineers."

At Systematix I worked on the controls team doing machine vision, system integration, industrial robot programming, and PC programming. I performed proof of principle analysis for future machine vision jobs in the vision lab and also setup vision systems on production machinery.- Integrated PLC, HMI, vision, data collection, and peripherals on production machinery- Programmed 6-axis industrial robots for vision-assisted pick-and-place routines- Troubleshooted mechanical, electrical, and software issues on assembly line with diverse team- Setup cameras, lighting, and inspection software for industrial machine vision systems- Conduct machine vision lab evaluations for purchase order estimates and proof of principle studies- Setup Git server and teach workflow to other developers- Developed HMI frontend for automated IV bag inspection machines using C# and WPF- Created new form for documenting purchase order lab evaluationsFrom manager:"Jeff has demonstrated his ability to learn new skills (vision/PLC/robot) and use his existing skills (PC software/documentation) to make this an outstanding work term for us here at Systematix.

At Providius I worked mainly on their video stream analytics platform, focusing on developing data visualisation tools and other features for their web-based dashboard. I also worked on their tablet platform and began laying the foundation for more code portability between the two products.- Integrated Chromium Embedded Framework with Qt to enable code portability between PC and web products- Redesigned web-based audio meter using SocketIO and D3.js to display real-time data for video streams- Rewrite real-time bitrate graph using SocketIO and Dygraphs to increase sampling rate up to 60x- Ported data analytics administration dashboard to Ionic (Angular) framework- Rapidly developed prototype features for customer demos and trade shows- Upgraded PC platform to latest Ubuntu LTS for better support and longevity- Setup HTTPS communication using OpenSSL and NGINX to improve login securityFrom manager:"Jeff was a fantastic co-op and a pleasure to work with. He brought in existing expertise on angular front end design and helped us achieve organizational knowledge in this area. He went above and beyond in keeping detailed notes and documentation. He was punctual, hardworking and an eager team contributor."

At Wind River I worked in the Technical Publications team on the customer training portal. I also developed various smaller tools for internal use.- Added new support user type to web application to reduce monthly server cost by $300+- Lead major platform upgrade including complete frontend rewrite to Anuglar for web training portal. Thoroughly documented process for project handover- Developed web application to automate synchronizing production builds across office locations- Created compatibility layer to port 20+ automated test cases from Linux to Windows IoT platform in first week- Implemented login layer for admin tools web application using MongoDB and NodeJS From manager:"Jeffrey also took on a major platform upgrade for our virtual lab environment and went beyond expectations by providing a migration path in addition to refactoring most of the code base and ensuring basic functionality was working.""An amazing work term: Jeff has handily ramped up on any necessary workflows and tools, and quickly became productive. He is very diligent in his work and puts in an effort to do a good job. He is also very successful in taking on challenges outside his comfort zone.""His work here will have a lasting impact on both product and internal tools."
