Worked on the zowe-cli repository to enhance KeychainAgent’s TLS handling and cross-platform compatibility for both macOS and Windows. Focused on refactoring the TLS workflow to support exportable and non-exportable keys, improving pipe timing, and expanding error context with detailed handshake hints to streamline debugging. Leveraged Rust and TypeScript to implement Windows-specific compilation adjustments using the agent-base library, which simplified socket management and improved HTTPS connection reliability. These changes reduced codebase complexity, addressed Windows build errors, and accelerated issue resolution, resulting in a more maintainable and robust backend system for secure network communication and full stack development scenarios.
