Tamarm worked on the PubMatic-OpenWrap/prebid-server repository, delivering OpenRTB 2.6 support for the Undertone bidder. By updating the bidder configuration to declare OpenRTB 2.6 compatibility and adding the openrtb.version field with the value '2.6', Tamarm enabled new protocol features and ensured alignment with the latest industry standards. This change improved interoperability and reduced integration effort for partners using the Undertone bidder. The work demonstrated skills in configuration management and a strong understanding of the OpenRTB 2.6 protocol, with YAML used for configuration updates. No major bugs were addressed during this period, focusing solely on feature delivery.
