Hoonji contributed to the google/adk-python repository by developing a customizable Web UI logo feature, enabling users to define both text and image URLs for branding flexibility. This was achieved by updating the ADK WebServer to accept, persist, and serve logo configurations through a dedicated API endpoint, leveraging Python and JSON for runtime configuration management. Additionally, Hoonji addressed a reliability issue by ensuring the parent directory exists before writing evaluation set files, preventing runtime errors during file creation. The work demonstrated proficiency in backend development and web UI configuration, delivering targeted improvements that enhance deployment consistency and reduce operational failure points.
