Developed OpenRTB 2.6 support for the Criteo bidder within the prebid/prebid-server repository, focusing on enhancing compatibility with demand partners and expanding publisher reach. The work centered on updating YAML configuration files to integrate Global Privacy Platform (GPP) requirements and enable multi-format ad support, strengthening privacy controls and interoperability. Leveraging configuration management skills, the developer ensured that the new features aligned with evolving industry standards while maintaining clear, maintainable configuration structures. The changes addressed the need for broader integration opportunities, allowing prebid-server to support more complex bidding scenarios and privacy requirements through precise, standards-compliant YAML configuration enhancements and management.
