Hi, I'm Frengky Soritua Manurung. I'm an Site Reliability Engineer at DOKU. I specialize in Cloud Infrastructure, Kubernetes, Infrastructure as Code, CI/CD, Observability, and Automation — building reliable, scalable systems while improving monitoring, alerting, and operational efficiency, and implementing SLIs and SLOs to measure and maintain service reliability.

Outside of tech, I'm a big fan of FC Barcelona— Visca Barça!
