Martin Frohnholzer developed a comprehensive Friend Referral System across the corona-school/backend and corona-school/user-app repositories over two months. He designed and implemented backend logic in TypeScript and SQL to track referrals, including a referredById field and analytics for user acquisition and supported hours, ensuring robust data integrity through backend validations. On the frontend, Martin built a React-based referral UI that enables users to invite friends via social channels, view referral counts, and monitor hours contributed by referred friends. His work integrated new GraphQL queries and routes, enhancing both the data layer and user experience while supporting improved capacity planning and reporting.
