Work & Experiments

I build new ways for people to interact with computers—especially visual tools, sensor-driven interfaces, and on-device AI. Selected work from more than a decade of products, open-source software, and experiments.

Selected Work products, tools & experiments
Stitch Founding Engineer

An open-source, node-based prototyping tool for mobile interactions. I built its 3D system and worked across AR, computer vision, and AI-assisted graph generation.

Open SourceNode Graph3D
Asteroid Founding Engineer

A macOS node-based tool for building ARKit experiences without code. I built much of the app, including its node editor, project-export pipeline, and camera, audio, and CoreML nodes.

AudioKit — open-source audio framework for Apple platforms
AudioKit Founding Team

An open-source audio framework for Apple platforms. On the founding team, I helped prepare its public release through examples, tutorials, framework testing, and Sensible Defaults.

Roboflow iOS SDK — on-device object detection
Roboflow iOS SDK Creator

A native Swift SDK for deploying Roboflow computer-vision models on iOS. I led its development and built CashCounter, an App Store example with a feedback loop for improving the model.

ChromaSwift — Chroma's retrieval system, on-device for Apple platforms
ChromaSwift Creator

Chroma's official Swift SDK, built in collaboration with Chroma. I bridged its Rust core to Swift and added local MLX embeddings, on-device storage, and cloud sync.

Project Soli Alpha Developer

I explored mm-wave radar as a human-input modality through Google's Alpha Developer Program. The work led to a NIME 2017 paper on radar-driven musical interaction.

Touché Experiments — swept-frequency capacitive sensing with an air plant
Touché Experiments Independent

I built a swept-frequency capacitive sensing system and used machine learning to recognize gestures involving plants and water. Source on GitHub.
