Worked on the PubMatic-OpenWrap/prebid-server repository to upgrade Prebid Server from version 3.10.0 to 3.22.0, focusing on delivering new features and improvements aligned with the project roadmap. The upgrade process involved careful integration using Go, Docker, and GitHub Actions to ensure stability and traceability, with all changes merged through a clean pull request and documented commits. No major bugs were reported during this period, allowing full attention to feature delivery and upgrade reliability. This work enables the project to leverage enhanced bidding capabilities and performance improvements, supporting better outcomes for publishers and advertisers through robust backend development practices.
