              This is the control center for Asep Haryana Saputra&apos;s
              infrastructure. It monitors Docker containers, Traefik request
              metrics, Prometheus system resources, and Jaeger distributed
              traces across a multi-VPS deployment orchestrated with Dapr and
              NATS.
            </p>
            <p className="mt-3">
              The stack runs on Tailscale-connected VPS nodes with automatic
              service discovery, TLS termination via Traefik, and real-time
              streaming telemetry through JetStream-backed Dapr pub/sub.
