Trong Ngo contributed to the mezonai/mmn-tx-explorer repository by building real-time socket services and enhancing donation campaign analytics using Go, PostgreSQL, and WebSocket programming. He improved transaction search precision by shifting filters from block to transaction timestamps, ensuring more accurate time-based queries. Addressing security, he fixed refresh token lifecycle logic to prevent leftover tokens and improved error handling for token rotation. His work included designing new database schemas to track donations and withdrawals, as well as refactoring code for maintainability. Throughout, Trong demonstrated a methodical approach, delivering focused, auditable changes that improved reliability, data correctness, and end-user experience.

16 Commits • 2 Features
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.
