Worked on apache/shenyu and Duansg/hertzbeat, focusing on backend infrastructure, analytics integration, and security. In apache/shenyu, migrated the end-to-end testing framework from Kubernetes to Docker Compose, introducing new synchronization and storage configurations to streamline testing and improve CI feedback. Enhanced WebSocket management by implementing namespace-aware session handling, aligning admin features with existing configuration logic. For Duansg/hertzbeat, migrated analytics from Google Tag Manager to Matomo, prioritizing privacy by disabling cookies and standardizing URL handling. Addressed security vulnerabilities through dependency updates. Utilized Java, JavaScript, and Docker Compose, demonstrating depth in distributed systems, configuration management, and privacy-focused web analytics solutions.
