Case studies
Selected work across AI product design, enterprise SaaS, fintech, and high-trust consumer products, each a deep dive from problem and research through prototypes and outcomes.
Fetch, wind against lake geometry
Eight lakes, seven days, 448 scored blocks. Fifteen cosine weighted rays fan across every shoreline at thirty six wind bearings, so the polygon becomes arithmetic rather than a picture. Ninety two recorded decisions with every rejected alternative kept, including the model that passed every automated test while being algebraically a constant.
View case studyWatchtower, live agent supervision
A live supervision surface for autonomous voice agents: see what the agent is about to do before it does it, scope what it may touch, interrupt, and take over cleanly. A concept for Vida.
View case studyConformly
A compliance agent for the European Accessibility Act that delivers accessibility work as evidence: deterministic detection mapped to EN 301 549, fixes shipped as real pull requests, and a hash-chained, tamper-evident audit trail. It never tells you you're compliant. Honest status is the product.
View case studyNotification Sieve
A calm, context-aware filter that intercepts the noise, escalates only what matters, and lets you catch up on your terms.
View case studyKeySign
How spotting a real-world signing gap became a high-impact, secure digital-signature proof of concept.
View case studyHow Much Would I Have If
A what-if investment calculator with ~1,070 statically generated pages, real market data, built to earn its long tail honestly.
View case studyVantage, time to insight
Turning a sea of fragmented incident signals into one line to the cause: hand-built, accessible service-topology and flame-graph views, an AI read-lane, and a deliberate handoff to Oversee for execution.
View case studyDreadRobot
A skeptical review site for AI automation tools. A five-axis Dread Score, hard-cap disqualifiers, and a build-time guardrail that makes shipping a fake verdict a compile error.
View case studyRange, iOS rehab form coach
A doubt removal machine for solo knee rehab. On device pose estimation corrects form in real time without making a vulnerable person feel watched, and shows range of motion climbing week over week. Three live interactive moments, and the hard tradeoff made in the open.
View case studyReadout, data and dashboard design
Data visualization. The judgment behind a good dashboard: the right chart for the question, honest scales, drill-down on demand, and accessibility built in, not bolted on.
View case studyThe Interaction Layer
A masterclass in how software feels, built on seven principles of interaction design, each grounded in HCI law and proven with a live, hands-on demo you can run on the page.
View case studySignal Inbox
A unified context feed, powered by replay intelligence, that helps support agents resolve complex conversations faster.
View case studyPersonalization Tuning Studio
A design-led approach to large-scale personalization: explain model behavior, simulate change, and decide with confidence.
