Developed and integrated the RTBStack Bidder Adapter for the prebid-server repository, enabling support for banners, videos, and native ads as a new demand source. Focused on robust API integration and backend development using Go, the work introduced comprehensive input validation and structured request handling to ensure reliable communication with RTBStack’s bidding system. Enhanced error handling was implemented to gracefully manage invalid inputs and responses, improving overall system reliability and debuggability. The modular adapter design adopted in this feature lays a foundation for easier future integrations and maintenance, expanding inventory and potential revenue while emphasizing thorough testing and maintainable code.
