Worked on the dragonflydb/dragonfly repository, focusing on configuration management and server reliability using C++ and system programming skills. Developed the CONFIG REWRITE command to enable atomic persistence of runtime-modified configuration flags, ensuring that only relevant changes are written while preserving startup-only settings. This approach reduced configuration drift and improved restart reliability by reading the existing configuration and updating it safely. Additionally, addressed server stability by modifying signal handling to ignore SIGHUP, preventing unintended termination when the parent shell exits. These contributions enhanced uptime and session stability, reflecting a methodical approach to reliability and maintainability in server development.
