Over two years, I managed the design and development of a national disease surveillance dashboard that transformed how Vietnam's CDC tracked and responded to COVID-19. What started as an internal tool became a critical public resource, attracting 170,000 visitors within its first year of public launch.

This project aimed to support scientists and researchers in disease control efforts. Initially launched for internal study purposes, the website was made publicly accessible in December 2020, attracting 170,000 visitors by December 2021. To further enhance data encryption and safeguard patient privacy, it was later taken offline for maintenance.

The Challenge When Vietnam's second COVID wave began, manual Excel tracking was the standard. At first, 100 cases seemed manageable. But this approach had fundamental flaws: it was slow, error-prone, and provided no real-time visibility for decision-makers. As case numbers grew, the limitations became critical, researchers and policymakers couldn't see patterns, trends, or resource needs fast enough to respond effectively.

The Opportunity We recognized that the real problem wasn't just data volume; it was access to actionable insight. Public health officials needed real-time visibility into case trends to make informed decisions about resource allocation and public communication. Scientists needed to see patterns. The public needed transparency.

What We Built A comprehensive, real-time dashboard that transformed fragmented data into clear, actionable insights. By integrating multiple data sources into a single interface, officials could monitor trends, identify hotspots, and allocate resources efficiently, all in real time.

Impact & Evolution The dashboard launched internally, then went public in December 2020. Within a year, 170,000 people were using it to understand the pandemic. When security and privacy concerns emerged, we took it offline to implement enhanced encryption and safeguards, prioritizing data protection over continued access
