About
Hi, I’m Jinsoo Heo — a DevOps Engineer at Chronicle, the decentralized oracle network securing DeFi protocols.
I build and operate Kubernetes-based oracle infrastructure on AWS EKS, drive GitOps adoption with ArgoCD, and design observability platforms with Grafana, Mimir, and Loki.
Previously, I worked at Dunamu (Upbit) and PUBG, where I focused on high-availability infrastructure, service mesh, eBPF-powered observability, and DDoS protection at scale.
What I Write About
- DevOps & Infrastructure — Kubernetes, GitOps, CI/CD, Terraform
- Observability — Grafana, Prometheus, Loki, eBPF
- Web3 — Oracle infrastructure, on-chain data delivery, DeFi security
- Programming — Go, Python, system-level engineering
