Rafał Golarz

Worked on the heroiclabs/hiro repository, delivering four backend features over three months with a focus on system robustness and user control. Enhanced error handling in the Hiro GDK by introducing new error definitions, improving error classification and propagation for greater reliability. Refactored economy configuration by replacing a boolean flag with a dedicated setter, increasing clarity and testability. Developed an unenrollment feature for event leaderboards, updating gRPC and protobuf interfaces to allow users to opt out of cohorts and improve data integrity. All work was implemented in Go, emphasizing maintainability, clear documentation, and seamless integration with existing backend systems.
