STATUS

system overview

I'm Duc Dinh, a DevOps & Site Reliability Engineer based in Ho Chi Minh City, Vietnam. I design and operate cloud-native infrastructure built to scale and built to last.

My journey started in the NOC — monitoring screens at 3AM, running incidents by runbook, learning what "reliability" really means at the ground level. That foundation shaped everything I build today: observable, automated, resilient systems.

Currently at Inspectorio, I operate the GCP/GKE platform behind an AI-powered supply-chain SaaS serving 12,000+ global brands & retailers — and I'm building an enterprise RAG system, an AI-powered SRE investigation assistant that turns incident context, runbooks and infra topology into answers.
