PROFILE

Jiewen Yao

Worked on the intel/MigTD and microsoft/MigTD repositories, delivering four features over three months focused on system programming, DevOps, and security. Enhanced the migtd-hash tool by implementing new hash calculations and improving documentation to streamline onboarding and data integrity verification. Automated governance processes with CODEOWNERS-based reviewer assignment and refactored policy verification modules for clearer, more maintainable code. Upgraded core dependencies such as quinn-proto, zerocopy, and spdm-rs, aligning APIs and reducing unsafe code to improve stability and performance. Leveraged Rust and asynchronous programming to ensure robust dependency management, memory safety, and cross-repository compatibility throughout the development lifecycle.
