What I'm looking for

I’m looking to lead platform and infrastructure engineering—designing Kubernetes/GitOps systems, strengthening developer experience, reliability, and observability, and delivering secure, compliant AWS multi-account platforms that scale.

I’m a principal-level infrastructure and platform engineer with 13+ years of experience building and operating high-load distributed systems across AI, blockchain, HFT, and AdTech. I specialize in turning complex infrastructure into stable, scalable platforms.

I’ve scaled Kubernetes platforms to 3,000+ nodes, designed multi-account AWS organizations, and built GitOps pipelines (GitHub Actions → ArgoCD → Kargo) to deliver code, configuration, and AI models across hundreds of microservices. I led platform engineering that improved developer experience and reduced compute costs by ~20% using Karpenter/KEDA autoscaling and workload profiling.

I’ve also led teams of up to 12 engineers and driven org-wide platform strategy, with multi-layer observability (Grafana, Loki, Tempo, Mimir, OpenTelemetry, Pyroscope) and SLO-based alerting. Security and compliance are central to my approach—SOC2/ISO27001 using Vault, External Secrets, SOPS, OPA/Gatekeeper, and Checkov—plus practical automation like custom Go controllers for DNS monitoring and failover.
