PROFILE
Liang Geng
Worked on apache/sedona-db to enhance GPU-accelerated spatial data processing by upgrading RAPIDS RMM for improved memory management and addressing a race condition that previously caused instability under heavy workloads. Developed comprehensive documentation for GPU-accelerated spatial joins, clarifying prerequisites, execution stages, and performance tuning to support user adoption. Implemented a new Rust method for concatenating evaluated geometry arrays, improving spatial data handling and robustness through error handling and testing. Addressed Windows build path limitations and unified rust-cache configuration, streamlining CI/CD workflows and ensuring cross-platform reliability. Leveraged Rust, CMake, and GitHub Actions to deliver stable, well-documented, and maintainable features.
