Worked on the XTLS/Xray-core repository to implement geodata-driven domain and IP rule management, focusing on DNS configuration enhancements and memory optimization for iOS. Refactored geodata handling using Go, introducing a new data structure and a memory-optimized domain matcher to improve rule accuracy and reduce resource usage on constrained devices. Enhanced sniffing configuration by extending domain exclusion to support geosite rules and adding IP and CIDR exclusions, increasing flexibility for geolocation-based policies. Leveraged skills in DNS management, backend development, and protocol design to deliver features that improved runtime efficiency, configuration granularity, and policy safety without introducing new bugs.
