Epilog

AI caught a drug interaction. The neurologist confirmed it.

HealthcarePersonal AIWearables-adjacent

An app built for one user with epilepsy. It's used daily to log events as the user experiences them. The AI Insights built into the app used the tracked data to surface an adverse drug interaction. A drug prescribed by the user's primary care physician was inhibiting the absorption of the anti-epileptic drugs the user depends on. This information was brought to the neurologist and they confirmed the interaction. The neurologist independently arrived at the same treatment direction the AI had suggested.

Sim Racing Coach

Race-engineer practice, designed into an AI product.

MotorsportsAI ProductsDomain Depth

Design consulting on an AI sim-racing telemetry tool. Reframed the analysis app as the AI agent's workspace, not a chat panel beside it. Designed a race engineer pattern that translates expert practice into UX for sim-racers who don't have an engineer. Four worked archetypes shipped against the product's telemetry schemas.

Brightly

Design direction for a $1.575B acquisition.

ManufacturingHealthcareEducationGovernment

Vision design across 12 siloed products at Brightly. A unified design language and integration model proposed across the portfolio. Designs were used in acquisition-stage presentations to Siemens to demonstrate the platform vision and integration roadmap. Brightly was acquired for $1.575B.

Power Quality and Demand Response

AI insight, operator decision. 200+ industrial locations.

EnergyIndustrialOperator UX

Operator surfaces for AI-powered energy intelligence. Power Quality and Demand Response as two distinct operator views on one underlying AI system. Deployed across more than 200 industrial sites of a single customer. Penalty avoidance was the structural value, not a measured-savings claim.

About

What I do, and why this site is a transit map.

I'm a senior product designer and design leader. That's fifteen years of designing complex software, mostly enterprise, having led both onsite and full remote global teams. At Brightly I ran the accessibility program across four markets, and led an effort to unify a portfolio of 12 siloed products into a singular experience. Now I'm in Berlin doing the independent version of the same work, building and shipping AI products on my own. I hold US and German citizenship, with full EU work authorization.

This site is built around a transit map, for my love of transit and simple clear design. A subway has to work for a tourist who doesn't speak the language, a commuter running late, a child riding alone, an elderly rider with a cane, and somebody running on no sleep at the end of a long day. The route map, the signage, the ticket machine, even the industrial design of the train, the platform, and more, all have to offer the same accessibility and clarity for every one of those people, in seconds, with no instructions. I strive for my design work to do the same.

Away from the screen it's mostly wheeled things. I've been a cyclist since the 90s and I still ride on and off road around Berlin. I also build and prep cars for track driving, and I coach other people who are learning to drive at the limit. Getting someone faster means understanding what has to happen and what can go wrong before it happens, communicate, and execute. That transfers directly to running a design team.

The illustrations below are mine. I like drawing cars to keep my eyes and hands in sync.
