Infrastructure / Software delivery
Production infrastructure
Deployment and operation of containerized applications on a single-node Kubernetes platform, with GitOps, observability, and tested recovery procedures.
Engineering scope
- Application delivery
- OCI-hosted k3s, container workloads, Traefik ingress, immutable images, and reviewed Argo CD GitOps promotions.
- CI and verification
- GitHub Actions with isolated self-hosted ARM64 execution, automated checks, and explicit production release gates.
- Observability
- Prometheus and Alertmanager monitoring, operational alerts, and incident response procedures.
- PostgreSQL operations
- CloudNativePG with Barman Cloud object-storage backup and WAL archival; an isolated point-in-time recovery test verified restored application data.
Deployment boundaries
The cluster is single-node, not a high-availability installation. Application image promotion is separate from database migrations and backup verification. The CloudNativePG adoption program includes a separately validated backup and recovery path; migration of existing application databases remains a distinct operational decision.
