Turning complexity into products
people can actually use.
A product and systems designer — I think in feedback loops and incentives, not just screens: what a system rewards, what it makes visible, what it quietly optimizes for. A decade on the hardest problems in healthcare — clinical reasoning, AI trust, the architecture of the electronic medical record — plus systems I design and build myself, up to a six-layer commons operating system. I work at staff and principal scope. Currently at Tebra.
Integral Commons
What would civic infrastructure look like if it optimized for coherence, care, and regeneration instead of engagement, profit, and efficiency? A six-layer commons operating system — and the design thinking behind it.
Taskr
A hierarchical task manager built around a single insight: seeing everything makes it feel like you need to do everything. Snooze entire subtrees, surface them when you're ready, and keep the hierarchy as the primary mental model.
Tebra
The work behind the EHR isn't just visual design — it's an argument about what a clinical record is for. The push from encounter-based notes to a Problem-Oriented Medical Record, with entities instead of sections and AI as a real participant rather than narrative wallpaper.
TPM — A Decision Support Dashboard
A React dashboard sitting on top of a multi-sport ML betting pipeline — the design problem isn't 'show the data,' it's 'help the user decide.' Outcome review, governance control planes, and a parlay builder that respects model uncertainty.
Designing Experiences: A Philosophical Exploration
The words experience, user experience, customer experience get thrown around a lot. Let's explore them a bit more.
Measuring Subjectivity in Interface Design
Assessing cognitive appraisals of interface designs using desirability studies and statistical analysis.
Open to conversations
About staff and principal product design roles — and the occasional consulting engagement. If you're working on a problem that isn't yet well-defined, that's where I'm most useful.
