Summary

I'm a DevOps engineer. Most of my day is CI/CD, infrastructure-as-code, and observability: the plumbing that lets a team deploy without holding their breath. What I actually enjoy is the layer below the tools: what happens after `kubectl apply`, why a node went NotReady, where a request goes after it leaves the load balancer. I find systems a lot easier to run once I understand them down to that level, so that's where I tend to spend my time.

Experience

Mybit Innovation Lab · DevOps Engineer

Mar 2026 – Present
Tangerang, ID · Hybrid
  • Technical owner of the monitoring platform for Wero, a European product: designed the monitoring architecture, rules engine, customer-side agents, and alert routing.
  • Cut a service's recurring AWS bill from ~$200/mo to $3/mo after tracing the cost to needless payload transfers and redesigning the integration.
  • Migrated application file storage to S3, with a structured object hierarchy and IAM role-based presigned-URL access to tighten who can read what.
  • Built the observability stack (Grafana, Prometheus, Loki, Alloy, Healthchecks.io) with automated onboarding, so a new service shows up in the dashboards on its own.
  • Standardized delivery with Gitea Actions pipelines, PR validation, conventional commits, and semantic versioning, plus IaC in Terraform and Ansible.

Charoen Pokphand Indonesia · System Administrator Intern

Mar 2025 – Feb 2026
Ancol, Indonesia
  • Led the migration of 50+ internal apps from Docker Compose to production Kubernetes, implementing GitOps delivery workflows.
  • Deployed APIMAN API Gateway secured via Keycloak IAM and LDAP, with Traefik as reverse proxy managing ingress and traffic routing.
  • Built a React-based backup system on XenAPI, replacing XCP-ng Pro and saving $1,000+ in annual license fees.
  • Migrated 10+ VMs from VMware to XCP-ng, including HA setup, recovery testing, and first-layer troubleshooting.

Bina Nusantara University · Junior Laboratory Assistant

Aug 2023 – Feb 2025
Tangerang, Indonesia
  • Delivered hands-on instruction to 1,200+ students across Linux Administration, Networking, Big Data, and Deep Learning.
  • Designed troubleshooting-focused case studies and maintained lab VM environments (Docker, Ansible, Proxmox, Cisco).
  • Completed infrastructure projects spanning network automation, full-stack development, and applied computing.

Featured Project

Reproducible Libvirt Infrastructure for Kubernetes Clusters

Going from a bare hypervisor to an HA Kubernetes control plane entirely from code. No clicking through UIs, no nodes I configured once and could never reproduce.

  • One command brings up the networking, storage, and a bootstrapped cluster, then tears it all down and rebuilds it the same way the next time.
  • Kube-VIP gives the control plane a virtual IP with automatic failover, so losing a node doesn't take the API down with it.
  • I wrote the whole thing up end to end, so next time I (or anyone reading along) can follow the same path instead of rediscovering it.
