During November 2025, Alex developed the Clydo Advertising Adapter for the prebid/prebid-server repository, enabling support for banner, video, and native ads through robust API integration. Working primarily in Go, Alex focused on backend development and implemented comprehensive error handling to manage invalid requests and ensure input validation. The adapter was designed with stability and scalability in mind, featuring extensive unit and integration tests to verify functionality and reduce integration risk for publishers. This work expanded the range of supported demand sources, enhanced publisher inventory compatibility, and laid a foundation for potential revenue growth, demonstrating depth in testing and backend engineering practices.
