Worked on the mezonai/mmn-tx-explorer repository, delivering features and fixes focused on backend reliability and real-time data handling. Over three months, implemented a PostgreSQL-backed real-time socket service using Go and WebSocket programming, enabling interactive event-driven communication for users. Enhanced the donation campaign system with new database schemas to support detailed tracking and analytics. Improved transaction search precision by shifting to transaction-level timestamp filtering, strengthening data accuracy for time-based queries. Addressed a critical refresh token lifecycle bug, refining error handling and security. The work emphasized maintainability, clean commit history, and robust backend architecture, leveraging Go, SQL, and configuration management skills.

Dec 1, 2025December 2025: Implemented a PostgreSQL-backed real-time socket service with WebSocket and HTTP APIs, enabling reliable event-driven communication and interactive user experiences in mezonai/mmn-tx-explorer. Introduced Donation Campaign System Enhancements with a new DB schema to track withdrawals, recent donations, and intermediary wallet and red envelope tables. Performed targeted bug fixes and refactors to improve stability, readability, and maintainability, including cleanup of redundant files, formatting updates, and data-type adjustments (userid from int64 to string). These efforts deliver real-time engagement capabilities and robust donation analytics, driving business value and reducing maintenance overhead.

Nov 1, 2025Month 2025-11: Consolidated security and reliability gains in the mezonai/mmn-tx-explorer project by delivering a critical refresh token lifecycle bug fix. The fix ensures the old token is deleted only after the new token is successfully set, enhancing security and reducing risk of leftover tokens. Improved error handling around token rotation to prevent partial token states and to surface issues earlier.
