Worked on core backend components in the pion/ice and pion/interceptor repositories, focusing on code quality, security, and performance improvements using Go. Addressed static analysis warnings and linting issues by refactoring code and reformatting deprecation comments, ensuring compliance with security standards and Go best practices. Enhanced reliability by optimizing UDP listening logic to reduce CPU usage during network interface changes, with robust error handling for both POSIX and Windows environments. Expanded test coverage across multiple platforms, including Linux, macOS, Windows, and WASM, and maintained clean runs with golangci-lint. Prioritized maintainability, observability, and cross-platform compatibility throughout development.
