Over a two-month period, contributed to the nccasia/mezon and nccasia/mezon-fe repositories by focusing on both integration reliability and new feature delivery. Addressed configuration management for the Treasury withdrawal system, updating environment variables to ensure the chat application interacted correctly with new deployments. Later, developed a Webhook node for mezon-fe, enabling real-time HTTP integrations and introducing a modal-based token management UI to streamline flow creation and execution. Utilized JavaScript, TypeScript, and React to implement these solutions, emphasizing robust state management and UI/UX improvements. The work balanced backend configuration hygiene with frontend component development to support evolving integration needs.
