SENIOR DEVOPS · SITE RELIABILITY ENGINEER · CKA & AWS CERTIFIED · KUBERNETES AT SCALE
Senior DevOps / SRE who keeps large multi-cloud Kubernetes fleets fast, cheap and reliable.
5+ years supporting complex distributed systems in production. I turn manual, costly operations into automated, self-healing platforms: GitOps delivery, autoscaling, and progressive rollouts on hundreds of Kubernetes clusters across AWS, Azure, GCP and Linode.
My instinct is to engineer toil out of existence: find the recurring incident or slow process, automate it, and hand the team back their time.
I stay calm and methodical during high-severity incidents, owning on-call and incident command through major live events and keeping customers informed under pressure. I also work well at the seam between infrastructure and people: I lead small teams, mentor engineers, and make reliability a shared default with product and software teams. A career-changer by design, from research biologist to senior SRE, I bring that same self-teaching drive to every new system I own.
Key Achievements
▸ Delivered 10× faster deployments and saved 100+ automation hours by standardizing deployments with GitOps (ArgoCD) and IaC across the fleet.
▸ Eliminated 20+ hours of on-call toil and 20–30 incidents per month by building automated OOM (out-of-memory) remediation.
▸ Replaced weeks of manual release coordination with automated, health-gated progressive rollouts by co-building a fleet-wide delivery platform on ArgoCD, Kustomize and Argo Workflows.
▸ Extended Prometheus observability to 30+ previously unmonitored environments, defaulted into every newly provisioned cluster.
▸ Cut AWS platform cost 27% and accelerated deployments 500% at Triggle; reduced EKS extended-support cost 82.5% via a 1.24→1.29 upgrade across 4 clusters.
▸ Cut compute cost by 80% across autoscaled workloads by rolling out Vertical and Horizontal Pod Autoscalers, driven by custom Prometheus metrics, to hundreds of clusters.
Professional Experience
Site Reliability Engineer — Hydrolix
Cloud-native, petabyte-scale streaming-analytics platform. Multi-cloud Kubernetes production fleet (300+ clusters, 20,000+ pods) across AWS, Azure, GCP and Linode, serving enterprise customers.
▸ Led fleet-wide reliability, cost, and delivery across hundreds of clusters: GitOps standardization, autoscaling, progressive delivery, and automated OOM remediation (see Key Achievements).
▸ Owned EMEA on-call and incident command for high-severity events, including major live broadcasts, and interfaced with customers to resolve reported incidents.
