Worked across apache/opendal and langgenius/dify repositories to deliver modular backend features, performance optimizations, and robust test automation. In apache/opendal, enabled user-configurable storage services in C++ bindings using CMake feature flags, improving build flexibility and reducing binary size, while also refactoring buffering logic for higher throughput. In langgenius/dify, modernized HTTP client usage by migrating from requests to httpx in Python, enhancing maintainability and performance. Focused extensively on test infrastructure, migrating over 20 SQL test suites to Testcontainers for deterministic, isolated integration testing. Demonstrated expertise in Python, C++, SQL, and CI/CD, emphasizing maintainable, scalable, and reliable backend systems.
