Aleksandar Crepuljarevic developed core features for Ogury integration within the Prebid Server ecosystem, focusing on backend enhancements in both the prebid-server-java and prebid-server repositories. He implemented inventory mapping for in-app traffic, supporting publisher IDs from both site and app contexts, and introduced robust publisher ID validation for ad requests. Using Go and Java, Aleksandar updated error handling and expanded unit tests to cover new validation logic and error scenarios, improving reliability and flexibility for mobile ad serving. His work aligned cross-repository workflows and increased validation coverage, addressing the needs of unified Ogury workflows without introducing new bugs.
