Worked on the mhsanaei/3x-ui repository to deliver security-focused backend enhancements over a two-month period. Developed and integrated IP banning features using Fail2Ban in Go, enabling the system to block new malicious connections without disrupting active user sessions. Improved client connection management by implementing IP-based access control and protocol validation, ensuring robust handling of Xray API ports and enforcing required fields for protocols like Shadowsocks. Enhanced code quality through targeted cleanups, standardized logging, and improved error handling. The work emphasized network security, API integration, and backend development, resulting in a more reliable and maintainable client management system.
April 2026: Completed security-focused enhancements for MHSanaei/3x-ui, centering on IP-based access control, protocol validation, and robust Xray API port handling. Implemented a safer IP ban workflow, clarified protocol requirements, and improved error logging and code quality to boost reliability and maintainability. These changes reduce disruption to legitimate users while strengthening access controls and API integration.
