During a one-month engagement, Xhw developed and deployed a dedicated portfolio development environment for the traPtitech/manifest repository, focusing on infrastructure management and DevOps practices. Xhw introduced Kubernetes manifests to define deployments, ingress, services, and TLS certificates for backend, frontend, and dashboard components, using YAML to codify infrastructure as code. The work included refining ingress rules to restrict API methods to GET and renaming certificate resources, thereby improving routing and security in the development environment. These changes enabled isolated development and testing, enhanced traceability through Git-based version control, and improved the overall developer experience without addressing major bug fixes.

Month: 2025-09 Summary: Delivered Portfolio Dev environment deployment and routing for traPtitech/manifest, introducing Kubernetes manifests and routing for portfolio-dev environment including deployments, ingress, services, and certificates for backend, frontend, and dashboard; updated application set with the new portfolio-dev path; refined ingress to restrict API methods to GET and renamed certificate resource to improve routing and security in the development environment. No major bugs fixed this month; focus on feature delivery and dev experience improvements. Impact: Accelerated development/testing with isolated portfolio-dev environment, improved security posture in dev, and better traceability of changes via commit history. Technologies/skills demonstrated include Kubernetes, manifests, Ingress/routing, TLS certificates, and Git-based version control.
