PROFILE

Yohei Ueda

Worked on the confidential-containers/cloud-api-adaptor repository, focusing on modularizing pod networking, enhancing CI stability, and improving deployment reliability. Delivered a centralized network configuration system and delegated tunneler setup to support pluggable backends, using Go and YAML to increase maintainability and scalability. Improved network configurability by parameterizing VXLAN ports and tunnel types, leveraging Kustomize and CI/CD pipelines to streamline deployments. Addressed cross-architecture build issues by refining Makefile profiles for s390x debug images, and stabilized agent onboarding by integrating an iptables wrapper in Dockerfiles. The work emphasized robust system design, containerization, and automation, resulting in smoother, more reliable cloud infrastructure operations.
