Worked on the nvidia-holoscan/holohub repository to deliver an upgrade of the PSD Pipeline to Holoscan SDK 4.0.0, focusing on improving compatibility and resolving version conflicts. The engineering approach involved refactoring the build process to use MatX headers directly and integrating CUDA libraries such as cufft, cublas, and cusolver, which eliminated the need for separate MatX build steps. Docker and CMake were used to streamline provisioning and align container base tags with new SDK requirements. The work also included updating documentation and branding to Voyager Technologies, enhancing maintainability and ensuring smoother deployments for future development cycles.
