Selected work
A preview of my role and approach. Open a project to explore the decisions, tradeoffs, and collaboration behind the work.
As Principal Product Designer, I owned the end-to-end platform experience, from shaping how marketers work with AI to the design system and engineering delivery.
I authored the system prompts and generation logic behind product-shot recipes and Sub Boards, translating creative intent into rules the model could act on.
I led the product from source audit to working prototype, turning 60+ pages of guidance into a shared model for finding, applying, and reviewing creative standards.
As Staff Product Designer, I led system delivery, managed agency component production, and aligned design with engineering so teams could adopt a shared foundation.
Currently building
Subtext
An AI companion for better conversations and self-understanding.
I’m building Subtext because finding the right words is only part of having a better conversation. Who you’re talking to, what’s happened before, and your own habits matter too.
Subtext brings that context together around each person in your life. It connects help with what to say now to patterns you can learn from over time, while letting you review and correct what it remembers.
