DevOps Engineer @ Chronicle — the decentralized oracle network securing DeFi protocols.
I own the reliability and infrastructure behind Chronicle's oracle publishing pipeline, ensuring continuous on-chain data delivery across EVM chains. Oracle downtime means DeFi protocol risk, so everything I build is designed for zero-downtime and rapid incident response.
🔭 Building and operating Kubernetes-based oracle infrastructure on AWS EKS
🚀 Driving GitOps adoption with ArgoCD app-of-apps pattern across multi-environment deployments
📊 Designing the observability platform — Grafana, Mimir, Loki, and Alloy — for oracle liveness monitoring
🏗️ Managing infrastructure-as-code with Terraform, Helm, and IPFS-based immutable configuration
🔥 Leading on-call and incident response for critical oracle infrastructure
🌱 Deep diving into eBPF and kernel-level observability
