The Challenge

Organizations needed a rapid, reliable solution to screen visitors and employees for COVID-19 symptoms while maintaining operational continuity. The system had to handle high-volume daily submissions, ensure data security and privacy compliance, provide real-time health insights for administrators, and be simple enough for users of all technical abilities to complete in under 2 minutes—all while being developed under pandemic time constraints.

The Approach

I designed and built a full-stack web application with a focus on security, usability, and scalability. The architecture included a multi-step health check wizard with real-time validation, secure authentication system with role-based access control, responsive design ensuring compatibility across all devices, and a powerful admin dashboard with filtering, search, and analytics. I implemented data encryption, automated daily health checks, and contact tracing features while maintaining a clean, intuitive interface that reduced user friction.
