Worked on the prebid/prebid-server and prebid/prebid-server-java repositories to deliver two configuration-driven features for the Consumable bidder. Introduced geoscope-based targeting by adding allowed country lists to the bidder configuration, enabling regional control and supporting regulatory compliance. Enhanced the YAML configuration to support endpoint compression and accepted currency information, improving deployment flexibility and monetization readiness. Focused on configuration management, API integration, and data serialization, with all changes tracked at the commit level for traceability. The work emphasized maintainable, declarative configuration using YAML, addressing business needs for regional targeting and operational efficiency without introducing new bugs during the development period.
