Jana Ranjani focused on improving build-system governance in the facebook/fboss repository by correcting BUCK build configuration ownership. Using Python and DevOps practices, Jana identified that on-call alerts were being misrouted due to outdated ownership mappings. She implemented a targeted fix that reassigned BUCK configuration ownership from dc_push_infra to the appropriate team, ensuring that build-related alerts now reach the correct service owners. This change enhanced accountability and streamlined incident response. Jana documented the new ownership mapping for future maintainability, collaborating across teams and following rigorous code review processes to institutionalize clear ownership handoffs and support ongoing build-system reliability.
