Worked on the microsoft/cpp_client_telemetry repository to enhance privacy guard testing and ensure schema alignment for telemetry features. Focused on expanding unit test coverage for the Privacy Guard Module using C++ and CMake, enabling more robust validation of privacy-related components. Updated the lib/modules submodule to the latest commit, aligning the project with the PG unified schema and supporting improved integration testing. No major bugs were addressed during this period, as the primary contribution centered on feature development and validation. Demonstrated skills in build systems, C++ development, and unit testing, contributing to reduced risk and improved integration readiness for telemetry releases.
