Over a four-month period, contributed to the WISVCH/gke-cluster repository by building and securing cloud infrastructure for production workloads. Delivered deployment scaffolding for major events, implemented gateway routing with domain accessibility, and migrated critical services to new endpoints. Applied Kubernetes and Helm to manage deployments, enforce TLS certificate governance, and streamline CI/CD pipelines. Enhanced operational reliability through health checks, memory tuning, and automated image updates, while strengthening security with secret management and service account controls. Used YAML extensively for configuration management, ensuring infrastructure as code practices. The work enabled faster feature delivery, improved security posture, and robust, scalable infrastructure management.
Month: 2025-10. This month focused on enabling production-ready payment capabilities and reinforcing security for critical features in WISVCH/gke-cluster. Key work centered on enabling live Mollie payments in chpay and securing BAPC scoreboard communications, with attention to deployment/config hygiene and credential handling to support reliable, compliant production operations.

September 2025 highlights for WISVCH/gke-cluster focused on security hardening, reliability, and infrastructure governance. Key outcomes include a revamped Keycloak deployment with version upgrades and an auto image update workflow using a custom Keycloak setup; a reliability fix for Keycloak healthchecks; TLS and certificate governance for Keycloak and the gateway; CHPay lifecycle improvements with memory tuning, extended health checks, and a generic health endpoint plus feature toggles driven by updated mail credentials integration; and a PV/domain workflow for Keycloak custom providers, including a temporary PV, domain configuration, and cleanup. These efforts collectively improve security posture, reduce risk of outages, accelerate safe production changes, and strengthen operational validation.

In August 2025, delivered foundational deployment for iap-testapp-spring in the release GKE cluster, establishing end-to-end readiness and security posture for upcoming user-facing features. Key work included deploying the app with health checks, HTTP route, image repository, and service definitions, ensuring Kubernetes discoverability and readiness for the release pipeline. Security hardening was applied by disabling serviceAccountName for the deployment to tighten how the app interacts with Kubernetes resources. No major bugs fixed this month; focus was on enabling a robust foundation for CI/CD and future features. Technologies demonstrated include Kubernetes/GKE deployment patterns, IAP integration, container registries, and service-account security practices. Business value: faster feature delivery, improved reliability, and stronger security for production deployments.

In April 2025, I delivered critical deployment scaffolding for bapc-2025 on the WISVCH/gke-cluster, established gateway routing with domain accessibility, hardened TLS certificate management, and migrated the scoreboard to bapc.eu to streamline traffic routing. These changes provide a scalable deployment path, improve security posture, and ensure reliable user access to the latest bapc scoreboard.
