In July 2025, Sajna Nazeer K delivered a security and memory-management enhancement for protected video streams in the rdkcentral/meta-rdk-video repository. She integrated a new API from gst-svp-ext to enable secure memory pre-allocation, implementing conditional logic in open_cdm_adapter.cpp to ensure memory is allocated only when required. This approach reduced latency and improved memory safety for video pipelines. Sajna also created a build-time patch to consistently apply the update across builds. Working primarily in C and C++, she demonstrated expertise in embedded systems development, media frameworks, and security, addressing a focused technical challenge with a well-scoped, maintainable solution.
