PROFILE

Alex Gu

Worked on the MaaAssistantArknights repository over a two-month period, focusing on stability, crash prevention, and deployment reliability rather than feature development. Addressed critical bugs in C++ code, including fixes for macOS PlayTools controllers, OCR accuracy, and gesture input reliability, while ensuring no public API changes. Improved concurrent programming by introducing atomic task counters and enhanced error handling in filesystem operations to reduce unhandled exceptions. Strengthened CI/CD security by pinning GitHub Actions to specific commit SHAs and improved release workflows. Emphasized robust, predictable behavior suitable for automated testing and multi-instance workflows, leveraging C++, YAML, and system programming expertise.
