Things I've Built
See all projects→Animated TV-headed robot avatars for Solid. Each head draws an LED face on a 2D canvas that shows an agent's state, such as thinking, searching, or speaking.
A background remover that runs on your own machine. It uses WebGPU and ONNX Runtime across a hosted web app, a local app, a batch CLI, and a Node API, and source images never leave the device.
A Solid port of audiocn/ui. Audio meters, visualizers, faders, knobs, a mixer, players, and sound pads, distributed as shadcn registry source.
An independently implemented Solid 2 renderer for GPUIX and GPUI. It connects Solid’s universal runtime and fine-grained reactivity to Zed’s GPU-accelerated UI stack.
A framework-agnostic browser inspection and visual context layer built with Solid 2 for measuring interfaces, annotating intent, and giving coding agents exact rendered evidence.
A native iPhone calorie and macro tracker with SwiftUI, SwiftData, widgets, barcode and nutrition-label scanning, optional sharing, and supporting Cloudflare/Convex services.
A versioned control contract for browser and desktop DAW operations, with typed SDK clients, MCP and CLI adapters, bounded JSONL transport, and packaged Electron acceptance.
