Contributed to the prebid/prebid-server repository by developing a feature that enhances bid request handling for the Relevant Digital adapter. The work introduced the useSourceBidderCode option, enabling more flexible bid responses when the server-side bidder code differs from the client-side, addressing a nuanced integration challenge. This feature was implemented in Go, leveraging backend development and API design skills, and involved close collaboration with the Relevant Digital team to ensure alignment with their requirements. The contribution focused on improving adaptability in server-to-client communication, reflecting a targeted and collaborative approach to feature development within a complex, production-grade bidding infrastructure.
