Who I am
Senior product design for complex decisions.
10+ years partnering with cross-functional, international teams to turn ambiguity into clear business outcomes.
From research and framing to flows, prototypes, and delivery, I work with product and engineering to create direction.
Across enterprise, AI, and operational products, I use systems thinking and accessible design to balance user needs, business goals, and technical constraints.

What I do
Making complex
product work clear
For enterprise, AI, and operational products where the decisions, and the consequences, are real.
- 01
End to end
Every product decision is carried from research and problem framing through flows, prototypes, build, and iteration.
- 02
Complex flows
Every complex flow is shaped around clear next steps, with accessibility, edge cases, and recovery built in from the start.
- 03
Structured for AI
Every content model and data point is structured so AI assistants and search engines can read, summarize, and cite it accurately.
