Hey, I’m Gatan 👋
“Turning infrastructure chaos into automated harmony — one pipeline at a time.”
I’m Renaldy Gatan Pramana, a DevOps & SysOps Engineer with 3+ years of hands-on experience designing, automating, and maintaining scalable IT infrastructure. From managing bare-metal servers to orchestrating Kubernetes clusters in the cloud — I bridge the gap between development and operations.
My journey started from the ground up as an IT support professional, and through relentless curiosity, I evolved into a DevOps practitioner who lives and breathes CI/CD pipelines, Infrastructure as Code, and observability stacks.
🚀 What I Do
I specialize in building robust, automated infrastructure that enables teams to ship faster and sleep better at night. Here’s what a typical day looks like:
- 🔧 Architecting multi-environment infrastructure across dev, staging, and production
- 🔄 Automating everything — from server provisioning to deployment workflows
- 📊 Monitoring systems with Prometheus + Grafana dashboards and smart alerting
- 🐳 Containerizing applications with Docker & orchestrating with Kubernetes
- 📝 Documenting runbooks, architecture diagrams, and SOPs for operational continuity
