Worked on the langgenius/dify-plugins repository to deliver and stabilize the Polardb4AI DB Agent, focusing on deployment and language processing reliability. Developed a binary package to enable reproducible deployment workflows, ensuring traceability and easier rollout in plugin-driven environments. Addressed a language handling bug through binary-only edits, demonstrating careful change management and validation to minimize impact on existing workflows. Utilized skills in binary packaging, deployment automation, and language processing, with attention to supporting multilingual data scenarios. The work emphasized maintainability and operational stability, laying the foundation for scalable deployment and robust language support within the Polardb4AI DB Agent ecosystem.
