SYSTEM ROBUSTNESS.

>> ENTERPRISE CLOUD ARCHITECT & HARDENED LINUX SYSTEMS ENGINEER

I build resilient, automated container platforms and cloud infrastructure. Squeezing maximum uptime out of systems via IaC and Kubernetes is not my job—it's my baseline capability.

ronald@cloud-engine:~$ cat about_me.txt

I don't just deploy infrastructure; I engineer the digital backbone of modern enterprises. In the cloud, downtime is lost revenue. Operating deep within GCP, AWS, and Azure, I specialize in architecting highly available, fault-tolerant environments that scale dynamically and protect the bottom line.


I replace fragile manual processes with ironclad, immutable infrastructure using Terraform and Kubernetes. Whether it's executing zero-downtime deployments, enforcing strict zero-trust security, or drastically reducing compute costs, I deliver cloud solutions that businesses can bet their entire operations on.

PROFESSIONAL_EXPERIENCE

Real-time trails of production infrastructure deployments.

> 2024 - PRESENT

[ ENTERPRISE CLOUD ARCHITECTURE ]

ENV: GCP | AWS | AZURE

  • Architected multi-region, highly-available environments across public clouds.
  • Executed aggressive cost-optimization strategies and disaster recovery plans, ensuring infrastructure scales seamlessly with traffic spikes while maximizing ROI.
> 2023 - PRESENT

[ KUBERNETES & CONTAINER PLATFORMS ]

ENV: GKE | EKS | AKS | DOCKER

  • Commanded large-scale production deployments on managed Kubernetes services.
  • Implemented zero-downtime rollout strategies, hardened cluster security via strict RBAC, and optimized pod allocation to squeeze maximum performance out of every node.
> 2022 - PRESENT

[ INFRASTRUCTURE AS CODE & SRE ]

ENV: TERRAFORM | PYTHON | CI/CD | PROMETHEUS

  • Transformed legacy workflows into immutable infrastructure. Forged advanced CI/CD pipelines in GitHub Actions that ship code flawlessly.
  • Dialed in comprehensive observability using Prometheus and Stackdriver to catch and resolve anomalies before they impact end-users.

Declarative Kubernetes manifests & local cluster blueprints.

ERPNext on Kubernetes
drwxr-xr-x erpnext_k8s

ERPNext High-Availability Ingress

Orchestrated a high-availability ERPNext instance on a local production Kubernetes cluster using Helm. Configured multi-node worker pools, persistent local-path volumes, Redis/Valkey caches, and gunicorn servers. Exposed securely to the internet via Cloudflare Ingress tunnels with HTTP host header rewrites.

Uptime Kuma
drwxr-xr-x uptime_kuma

Uptime Kuma HostNetwork Monitor

Architected a lightweight Kubernetes-native service monitoring daemon utilizing Uptime Kuma. Implemented hostNetwork-level namespaces to verify VLAN routing and ping access to internal PBX network nodes (10.10.30.10/11) with bare-metal hostPath persistence.

Multi-SaaS Launchpad
drwxr-xr-x saas_launchpad

Multi-SaaS Cluster Launchpad

Designed and coded a multi-tenant provisioning orchestration engine in Python Flask. Automatically deploys isolated client instances (Directus CMS, Vaultwarden, Umami, Ghost) in dedicated namespaces on a 3-node bare-metal Kubernetes cluster, handling NodePort routing and Cloudflare DNS edge tunnels.
