What I do

I help agencies and brands turn ambitious ideas into interactive experiences that work in the real world, on time and on the show floor.

  • Brand activations: Interactive installations for events, trade shows, sports and retail, for clients like Google, Shopify, Intel and Molson Canadian.
  • AI experiences: Generative AI installations built on Gemini and Imagen, such as Google Cloud's Infinite Nature and Infinite Fleurs.
  • Hardware and prototyping: Microcontrollers, LEDs, sensors, multi-touch, robotics and fabrication, from a quick proof of concept to a build that survives a crowd.
  • Technical direction: Scoping, architecture, working with fabricators and vendors, leading developers and mentoring teams through to install.

I'm based in Toronto, work remotely and travel for installs. I'm available for contract and freelance projects. Tell me what you're planning.

Experiments

Personal R&D: things I build to learn a new chip, tool or technique. Work in progress, with the code on GitHub.

In progress 2026

ESP32 Rive Player

Interactive Rive animations on a microcontroller touchscreen

  • Microcontrollers
  • Creative Coding

Plays Rive animations on a 720×720 touchscreen driven by an ESP32-P4, a microcontroller with no GPU. It supports state machines, touch, text, layouts and sound, so interactive Rive designs can run on a small, low-cost display.

PocketStream

Live video from TouchDesigner to a microcontroller display

  • Microcontrollers
  • Video Streaming

Streams live video from TouchDesigner, OBS or ffmpeg to a 720×720 display driven by an ESP32-P4. The board receives a standard RTSP stream over Ethernet and decodes it in software, turning a small, low-cost screen into a display any video tool can drive.
