Taishi worked on deploying the Emoine service within the traPtitech/manifest repository, focusing on robust configuration management and deployment reliability. He provisioned Kubernetes resources including Deployment, Service, Ingress, and TLS certificates, while managing environment variables and secrets through YAML-based manifests. To prevent unintended deployments, he refined Application Set configurations, ensuring Emoine was excluded from both main and sakura environments. Taishi also aligned cross-environment settings to minimize deployment errors and improve scalability. His work demonstrated a solid grasp of DevOps practices and Infrastructure as Code, delivering both a new service deployment and structural improvements to the repository’s deployment processes.
