Web Effects Pack
Fifteen film and print effects — burns, filmstock grades, crumpled paper, neon, a street light — running as real CSS/SVG/WebGL over live DOM instead of baked into a render.

Prototypes + experiments
Harvey's Lab
Solo projects I've been building with AI tools — some made in a single sitting, others over a week or two. Mostly Claude Code. I try stuff out and keep iterating on what sticks — little tools I actually use, prototypes still in motion, patterns I'm figuring out as I go.
I set the scope and review what the agents build. Verification depends on the project; Plover uses a byte-exact backtest and CI gates to catch output and copy drift.

the rest, newest first
Plover
A running-readiness app I took from a Jupyter notebook to a deployed private beta in about twelve days, leaning hard on AI agents. Built multi-user; so far I'm the only one on it.
Python/FastAPI/ReactDemo ↗
unit-of-trust
A scrollytelling essay arguing that agent decision legibility should be a first-class layer of the agent stack, not an afterthought.
Next.js/React/TypeScriptDemo ↗
local tutor
Fully local voice tutor for Mandarin and French — speak, it listens, replies, and talks back. Nothing leaves the machine.

observe-ui
Decision-legibility surface for autonomous coding agents (live cockpit + retrospective blame).
TypeScript/JavaScript/PythonGitHub ↗
Recommend Arena
Twelve recommendation-system designs benchmarked head-to-head on the same dataset and ground-truth queries.
Python/ChromaDB/NetworkXGitHub ↗
AI Pattern Testing
A living catalog of AI UX patterns — agent orchestration, tool-call visualization, adaptive cards and UI.

Journ
All-local, encrypted, voice-first journaling for iOS and macOS from a single SwiftUI codebase.
Swift/SwiftUI/SwiftDataGitHub ↗
Anagnori
Self-guided iOS exposure-therapy app, built around experiments rather than sessions. A working prototype I've tested on myself.

plytools
CLI for using Claude Code to brainstorm and track job applications.

RunTools
Browser-based running utilities — pace converter, heart rate zones, race predictor. Everything runs client-side.
