PROFILE
Gregory Lee
Over a three-month period, contributed to the nvidia-holoscan/holohub repository by modernizing application features and improving deployment workflows. Delivered a CV-CUDA compatibility upgrade to support NumPy 2.0, updating Dockerfiles and dependency management for multi-architecture support. Enhanced Python bindings for VisualizerICardioOp to maintain compatibility with Holoscan 3.7+, and resolved build issues in object detection modules by localizing dependencies in C++. Modernized the multiai_ultrasound pipeline for Holoscan SDK v2.8+, simplifying CUDA stream handling and addressing application stability. Work demonstrated proficiency in C++, Python, and Docker, with a focus on cross-version stability, maintainability, and streamlined user onboarding.

Apr 1, 2025April 2025 monthly summary for nvidia-holoscan/holohub. Key accomplishments include delivering a CV-CUDA compatibility upgrade to support NumPy 2.0 and updating the multi-arch deployment path to support x86_64 and aarch64. This work ensures CV-CUDA >= 0.11.0 is required, and the Dockerfile now installs the correct CV-CUDA wheel and Debian packages for both architectures. Impact includes smoother onboarding for users upgrading to NumPy 2.0 and reduced setup friction.
