Developed and integrated a persistent file logging system for the mhsanaei/3x-ui repository, enhancing operational visibility and auditability by enabling debug messages to be written to a dedicated log directory. This feature was implemented in Go and required backend development and system programming expertise to extend the existing console and syslog logging backends. The work included updating the in-memory UI buffer to support the new file logging structure, ensuring consistent and reliable logging across runtime components. The solution addressed troubleshooting needs by providing persistent logs, and the technical approach emphasized seamless integration with the project’s existing logging and UI subsystems.
