Worked on enhancing the Mobkoi bidder integration within the prebid/prebid-server-java repository over a two-month period, focusing on backend development and configuration management. Delivered a targeted update to the Mobkoi bidder endpoint configuration using Java and YAML, improving routing specificity and reliability for ad serving while simplifying future integrations. Subsequently addressed stability by removing the endpoint override, enforcing the default endpoint to reduce misconfiguration and runtime errors. These changes streamlined the configuration process, improved maintainability, and aligned with broader reliability goals for server-side bidding. The work demonstrated a methodical approach to incremental improvement and careful management of integration points.
