Population Scale Health Management Platform
Overview
In September 2022, I participated in an ambitious project at Google that aimed at establishing digital health records for an entire population in the state of Tamil Nadu.
This endeavor sought to create a centralized repository of health data for 18 million individuals, encompassing geographic, demographic, and social determinants of health.
Employing participatory design principles, we developed a purpose-built cloud-native platform. This initiative aligns with national digital health transformation plans, serving as a model for similar economies seeking to enhance population health.

Enabled consistency, efficiency and scalability in product development by providing a unified set of design principles, components, and guidelines.
Build for a Marathon
Not a Sprint
Used principles like progressive disclosure to reduce information density, elevate cognitive overload and reduce the working memory required for a task for a health worker
Color as a tool
for at-a-glance orientation
Used colours to culturally connect, guide attention for enhanced usability and enhance recall value by facilitating easier recognition and memory retrieval
Custom made,
unique Iconography
