Bakti Balamaru

I build and operate infrastructure that stays reliable under change — Kubernetes platforms, GitOps delivery pipelines, and secrets governance for production systems that can't afford surprises.

Currently a DevOps Engineer at PT. Mitra Pajakku, where I manage a production-grade Kubernetes cluster on RKE2 and lead GitOps workflows across a self-hosted GitLab + ArgoCD stack. Previously, as a DevOps R&D Engineer at PT. Datacomm Diangraha, I built CI/CD pipelines, monitoring, and identity systems for internal cloud services. My work spans the full infrastructure stack — from container orchestration and observability to secrets governance and data platforms — with a consistent focus on reducing operational toil.

Experience

Where I've operated infrastructure

Feb 2026 — Present

DevOps Engineer

PT. Mitra Pajakku

  • Manage a production-grade Kubernetes cluster built on RKE2, ensuring availability and controlled change across environments.
  • Lead GitOps workflows using self-hosted GitLab and ArgoCD, complemented by Fleet for Linux service management.
  • Introduced OpenBao as a centralized secrets management solution to strengthen credential governance across environments.
  • Carried out cross-data-center migrations of stateless applications and stateful workloads, including PostgreSQL, with minimal downtime.
Feb 2024 — Feb 2026

DevOps R&D Engineer

PT. Datacomm Diangraha

  • Built and maintained CI/CD pipelines with GitLab CI for internal engineering teams.
  • Implemented monitoring for Kubernetes clusters to improve visibility and reliability.
  • Designed a Single Sign-On solution using Keycloak and KrakenD for multiple internal cloud services.
  • Contributed to a multi-tenant, cloud-native ETL platform, and helped maintain a Database-as-a-Service offering and a Redshift-inspired data warehousing platform.
  • Automated service provisioning with Ansible.

Selected projects

Infrastructure I've designed and automated

GitOps Delivery Pipeline

Public repo

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.

  • GitLab CI
  • ArgoCD
  • Kubernetes
  • Docker

Nginx GeoIP Access Analytics

Public repo

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.

  • Nginx
  • GeoLite2
  • Telegraf
  • Grafana
  • Docker

MariaDB Galera Cluster Automation

Private repo

Ansible playbooks that stand up a MariaDB Galera cluster from bare servers, alongside companion playbooks for automated Metabase and Apache Superset installation — turning a multi-day manual setup into a repeatable, version-controlled run.

  • Ansible
  • MariaDB Galera
  • Metabase
  • Apache Superset
