Experience
Oscar Individual Enrollment Application
https://www.hioscar.com/individualsA React/GraphQL and Python/GRPC enabling users to enroll themselves in Oscar Healthcare.
A user first inputs a very limited set of demographic info to determine which plans they are eligible for. After selecting a plan, they are guided through the process of creating an account and enrolling, which only requires a little bit of information and a much smaller amount of time.
Technically speaking, what makes this application special is the push-down configuration engine. Healthcare is very complicated and each market Oscar operates out of has its own set of rules by which Oscar must abide. Based on the demographic info provided by each user, the application can be configured to represent the correct information, without adding complicated new logic each time these regulations are updated.
