Jwon focused on stabilizing the Weather Agent workflow in the a2aproject/a2a-samples repository, addressing compile-time blockers by aligning the agent to the latest A2A Java SDK version. Through careful build system configuration and detailed documentation updates in Markdown, Jwon resolved compatibility issues that previously hindered deployment across environments. The work included updating the README to guide developers through checking out and building the beta SDK, which improved onboarding and ensured CI consistency. By maintaining cross-language sample integrity, Jwon reduced deployment risk and supported a smoother multi-language workflow, demonstrating depth in troubleshooting and process improvement within a short project period.
