Vacina Votorantim

Public vaccination scheduling and operations for more than 65,000 citizens.

Vacina Votorantim was a vaccination scheduling PWA for the city of Votorantim, São Paulo. The public experience and administrative panel were built with Ionic, Angular, NestJS, PostgreSQL and AWS Lambda and S3.

The administrative workflow managed vaccination information, batches and appointments to help the city organize COVID-19 immunization.
