He transitioned from Java/Scala/Golang to Clojure and currently uses it as his primary language, reflecting a pragmatic appetite for functional programming. At Synacor Media and in open-source contributions to Prebid.js he improved header-bidding adapters by adding schain support, floors module compatibility, and modernizing bid fields—work that shows attention to industry standards and supply-chain transparency. He’s held senior engineering roles at iMedia/Mastercard where he combines ad-tech domain expertise with production-grade engineering.

Contributions summary:Rajkumar primarily focused on enhancing the `synacormediaBidAdapter` within the Prebid.js framework. Their contributions included implementing support for the schain object, which is crucial for supply chain transparency in header bidding. They also updated the adapter to use the tagId property instead of placementId and added support for the floors module, along with removing the adId from the bid response. These changes reflect a focus on improving the adapter's functionality and compliance with evolving industry standards.
