What I drove

Led prototyping for Horizon Home, shaping product direction across emerging hardware. Defined sprint strategy, aligned cross-functional teams, and brought clarity to ambiguous spaces.

What I built

High-fidelity prototypes across mobile + mixed reality, exploring new interaction patterns. Scalable systems for multi-device testing, enabling faster iteration and shared playtesting.

Impact

Influenced product and hardware strategy, with work featured in Meta Connect keynote. Helped teams make faster decisions, uncover cross-device challenges, and pivot early.

Key Contributions

  • Led cross-functional prototyping efforts, driving technical and UX solutions that informed product strategy and were featured in Meta Connect keynote.
  • Owned prototyping sprints end-to-end, aligning teams around vision, validating experiences on early hardware, and influencing roadmap decisions.
  • Developed scalable frameworks for multi-prototype testing and deployment, improving iteration speed and enabling broader team adoption.
  • Rapidly built and tested mobile + mixed reality experiences, uncovering cross-device challenges and driving product-level pivots.
  • Communicated complex ideas through polished prototypes, demos, and storytelling artifacts, increasing stakeholder alignment and decision-making speed.
  • Mentored and upskilled designers through tooling education and workshops, expanding prototyping capabilities across teams.

Constraints

Due to the proprietary nature of the work, this case study focuses on systems, methods, and prototyping practice rather than specific product outcomes.
