Designed and implemented a config system that enabled color’s Vaccine Product to enforce rapidly changing Covid vaccine requirements (age, at risk, dose) to help our customer’s deliver vaccines as soon as they became available. This config system was implemented on both front-end and backend which would enable us to do things such as add covid-19 boosters with a simple config change.
