Developed and integrated the Start.io Bidder Adapter for the prebid/prebid-server-java repository, enabling programmatic bidding with Start.io across banner, video, and native ad formats. The work involved implementing a new Java adapter class, defining YAML-based configuration properties, and creating comprehensive unit tests to ensure robust functionality. By supporting multiple ad types, the integration expanded the platform’s demand sources and monetization opportunities. The approach demonstrated proficiency in Ad Tech, Backend Development, and OpenRTB standards, focusing on maintainable code and test coverage. All changes were delivered in a single, well-documented commit, reflecting a methodical and focused engineering process within a one-month period.
