  • Meall

    An online food marketplace designed and implemented using the latest in web technologies. The back-end uses PostgreSQL, Docker, and Koa to provide secure user authentication and authorization. The front-end uses React.js, Sass, GraphQL, Apollo Client, and Redux to create an efficient, clear, and user-friendly user experience. The front-end uses a fully responsive design to allow for a seamless transition between mobile devices and traditional desktop computers.

  • Real-time Body Tracking

    Using a combination of lasers, fiber optics, and clever algorithms, we produced an inexpensive body movement tracking fabric. I worked on the data visualization to show in real time, the body movements reported from the fabric. The data visualizer used Python, OpenCV, Panda3D, Blende,r and QT to create a pleasing and attractive presentation.

  • Smart Heating

    A large-scale project involving hundreds of homes looking into and researching the nature of comfort, energy costs and user experience. I was completely responsible for taking the front-end designs and implementing, supporting, testing, and updating them for use on a range of devices including Android tablets and Windows laptops. The front-end work used AngularJS and directly interacted via a REST API to the smart algorithm's back-end. The front-end had full code coverage, complete end-to-end testing, and both mocked and live integrated tests, all running on a continuous integration system.

  • Underground Asset Tracking

    Underground asset tracking is a huge issue when it comes to such things as digging in the ground and trying to avoid hitting existing utilities. I worked on a universal mobile app which allows engineers to query and locate any underground cabling. The app initially targeted the iPad but was built with technologies which allowed for its subsequent port over to Android. The Titanium framework was used together with Java, Objective-C, and JavaScript to bring together all the essentials in connecting an iPad to a Bluetooth device and data visualizations for the assets via the Google Maps API.

  • Kinect Video Game UI

    The Xbox video games system introduced a very novel method of interacting in video games. It used Kinect technology to allow the user to use their full body motion to play games. I worked on integrating and adapting user interfaces to better suit the use of this technology and allow a more intuitive and fun experience. The user interface was largely built using Scaleform, ActionScript, and Flash for the visual elements and C++ for lower level optimizations and communication.
