Kyukawa worked on the vdaas/vald repository, focusing on backend and CI/CD infrastructure to improve reliability and developer experience. Over five months, Kyukawa enhanced build automation and workflow consistency by standardizing test environments with Makefile updates, refining Dockerfile dependencies, and introducing containerized CI processes using Docker and GitHub Actions. They improved onboarding and build stability for ARM64 environments, streamlined Helm and DevContainer setups, and addressed CI workflow gaps for forked pull requests. Additionally, Kyukawa contributed to code quality by cleaning up Protocol Buffer formatting and enabling richer benchmarking telemetry via gRPC, demonstrating depth in build systems and workflow automation.

In April 2025, delivered a reliability fix for CI workflows in vdaas/vald to properly handle forked pull requests when the ci/approved label is applied, ensuring linting and CI checks run regardless of PR origin. This addressed a gap where forked PRs could bypass essential quality gates, reducing risk in external contributions.

January 2025: Focused on stabilizing CI for benchmark and loadtest workloads in the vdaas/vald repository. Implemented a critical Docker build reliability fix by removing an unnecessary libhdf5-dev dependency across all Dockerfiles and added a Makefile adjustment to run ldconfig after HDF5 installation to ensure proper runtime linking. This work reduced docker build failures and increased CI stability for benchmark and loadtest jobs, enabling faster feedback and more reliable performance benchmarks.
