Developed and integrated an AI-powered payment service agent within the google/adk-samples repository, enabling secure payment and refund operations through conversational user interactions. Leveraging Python and Antom APIs, the solution focused on end-to-end payment flow validation and sample code refinement to support demo readiness and reference scenarios. The work demonstrated expertise in AI development, payment integration, and cross-team collaboration, resulting in a scalable approach to conversational checkout experiences. No major bugs were addressed during this period, but minor stability improvements were made to enhance the sample code’s reliability and usability for future demonstrations and validation of payment workflows.
