Contributed to the NordSecurity/nordvpn-linux repository by developing and refining backend features focused on reliability, security, and maintainability. Addressed network protection through dynamic killswitch rule updates and enhanced OAuth2 login flows with centralized logic and improved error handling. Strengthened mesh networking by securing private key lifecycle management and restoring key handling as needed. Improved test clarity and system resilience by refactoring VPN test helpers and making startup processes more robust. Fixed race conditions in analytics opt-in workflows by coordinating service initialization and state changes. Leveraged Go, Protocol Buffers, and gRPC, emphasizing error handling, system programming, and secure networking practices throughout.
