In the wake of the 2020 world pandemic, Apple and Google partner on COVID-19 contact tracing technology to protect people and get society back up and running. Since COVID-19 can be transmitted through close proximity to affected individuals, public health officials have identified contact tracing as a valuable tool to help contain its spread. 

By partnering with cross functional, product area (Google Play and Android) and company (Google and Apple) stakeholders, I led design efforts for Google Play, delivering high-quality solutions, influencing patterns and flows, providing multiple iterations and options of design.


When recognizing proposed solution wasn’t ideal, I challenged approach with alternative solutions, escalating when appropriate, and implementing real-time — sometimes conflicting — opinions and feedback from senior executives and leads.
