# About
role: "Cloud & DevOps Engineer"
location: "Indonesia"
about: >-
I'm a Cloud and DevOps Engineer with a strong focus on building reliable, scalable infrastructure from production Kubernetes clusters and GitOps pipelines to secrets management and cloud-native data platforms. I enjoy turning new technologies into practical solutions that reduce operational complexity for the teams I work with.
focus:
- "Kubernetes · RKE2 · Kubespray"
- "GitOps · ArgoCD"
- "Secrets Mgmt · OpenBao"
- "Minimal downtime Migrations"
- "Cross-DC Cluster Mesh"
summary: >-
Currently a DevOps Engineer at PT. Mitra Pajakku, where I run a production-grade RKE2 Kubernetes cluster backed by MariaDB, lead GitOps delivery through self-hosted GitLab and ArgoCD, and use Cluster Mesh to migrate stateless and stateful workloads like PostgreSQL across data centers with minimal downtime. Previously, as a DevOps R&D Engineer at PT. Datacomm Diangraha, I built CI/CD pipelines, Kubernetes monitoring, and an SSO layer with Keycloak and KrakenD, while contributing to a multi-tenant ETL platform inspired by AWS Glue and maintaining Redshift-inspired data platforms. My work spans the full infrastructure stack, from orchestration and observability to secrets governance and data platforms, with a consistent focus on reducing operational toil.
# Experience — Where I've operated infrastructure
experience:
- role: "DevOps Engineer"
organization: "PT. Mitra Pajakku"
period: "Feb 2026 — Present"
responsibilities:

projects:
- name: "GitOps Delivery Pipeline"
visibility: "Public repo"
description: >-
A GitLab CI + ArgoCD pipeline where every deployment to Kubernetes is driven by a single Git commit, no direct kubectl edit on the cluster. Application manifests live in one source of truth, so teams can't drift the running state away from what's declared in Git.

- name: "Nginx GeoIP Access Analytics"

description: >-
A monitoring stack that tracks which regions traffic to a web application is coming from, using GeoLite2 data resolved at the Nginx layer and visualized in Grafana useful for spotting unexpected access patterns by geography.
