Worked on enabling TDX_CAPABLE support for confidential computing workloads on Google Cloud Platform by delivering cross-repository features in both coreos-assembler and osbuild-composer. Developed Go-based configuration updates to recognize TDX_CAPABLE as a valid confidential type, adjusted machine-type selection logic, and ensured the TDX_CAPABLE shield is applied during image creation. In osbuild-composer, introduced guest OS feature support for TDX in GCP compute configurations, allowing newer RHEL and CentOS images to run as TDX guests. This work expanded confidential computing support on GCP, improved security posture, and streamlined provisioning for TDX-enabled workflows using cloud computing and operating system configuration skills.
