Weiwei Duan contributed to the livekit/rust-sdks repository by engineering cross-platform build stability and hardware-accelerated video features. Over seven months, Duan delivered Linux VA-API integration for NVIDIA GPU video encoding and decoding, stabilized Android and iOS build pipelines, and modernized CI workflows using Rust, C++, and CI/CD tooling. Their work included dependency management, patching build scripts, and updating system configurations to resolve platform-specific issues, such as ARM64 compatibility and WebRTC upgrades. By addressing both feature development and bug fixes, Duan improved runtime performance, reduced CI failures, and ensured reliable SDK integration for downstream developers across Linux, Android, and iOS.
