Yiming

Worked on StarRocks repositories over a three-month period, focusing on backend and API development, security, and cross-platform compatibility. Delivered impersonation support for the Query Detail API in crossoverJie/starrocks, enabling auditing and debugging under different user contexts using Java and JSON. Enhanced security in StarRocks/starrocks by restricting root process visibility when admin protection is enabled, mitigating sensitive data exposure. Improved macOS reliability in pinterest/starrocks by implementing manual shell script parsing to address BSD getopt incompatibility, stabilizing CI runs. Demonstrated a methodical approach to bug fixes and feature delivery, emphasizing code quality, testing, and collaboration across multiple repositories and environments.

January 2026: Cross-platform test harness improvements focusing on macOS reliability. Fixed macOS-specific command-line parsing in the test runner by adding manual parsing logic to handle BSD getopt, eliminating breakage in run-fe-ut.sh and stabilizing macOS CI runs. This reduces flaky tests, accelerates feedback loops, and lays groundwork for future cross-platform enhancements. Technologies demonstrated include shell scripting, OS detection, and BSD vs GNU getopt handling.

May 2025 monthly summary for StarRocks/starrocks focusing on key accomplishments and security improvements. Delivered a security-focused bug fix to enforce admin protection visibility controls: when admin protection is enabled, the root user cannot access or see the process list, preventing leakage of sensitive data. This aligns with the project’s security posture and access-control goals.
