Message

At PT. Sentra Vidya Utama (SEVIMA), I lead infrastructure, security, and platform engineering within the OpSec Division. I migrated the analytics platform from BigQuery to ClickHouse (BytePlus), reducing costs by 96%.

I also built and deployed a Go-based Docker CLI plugin for managing QA environments across eight engineering teams, and designed layered DDoS mitigation on AWS WAF. Before SEVIMA, I maintained cloud and on-premises infrastructure at Mitra Informatika and completed a DevOps Engineer internship at Practical DevSecOps.
