  • UI Software for a Parcel Storage and Collection Prototype

    This application combined Vue.js, Node.js, Bluetooth, and MQTT to deliver a hardware-ready SPA that allowed users to combine touchscreen interaction, smartphone app authentication, and Bluetooth beacon communication to deliver an intuitive parcel drop-off and collection experience.

    On-screen notifications and animations communicated the behind-the-scenes process to the user, with a Node.js microservice acting as an intermediary layer between the UI and the machine systems, talking over MQTT.

    The work was carried out with Intel NUC devices as the target, with R and D being carried out using Raspberry Pi as the target device.

    The result was a prototype which proved the feasibility of a production product.

  • Real-time Money Movement Tracking Visualization

    Working for Citi, I partnered with a blockchain team to demonstrate a near-real-time global money movement tracking prototype. This showed money movement from region to region with an eye-tracking animated UI, suitable for both professional and demonstrative use.
