Greg Carroll

Senior Site Reliability Engineer with 8+ years scaling and operating cloud infrastructure across fintech, blockchain, automotive and SaaS. I build reliability into systems end-to-end — observability, SLO-driven engineering and incident command — backed by expert-level Terraform and deep multi-cloud experience across AWS and GCP. My work spans monitoring transformations, Kubernetes architecture (EKS/GKE, multi-cluster), infrastructure-as-code and CI/CD automation in Go, Python and GitHub Actions.

Recent highlights: I cut mean time to detection by 40% by re-platforming monitoring from the LGTM stack to Datadog and version-controlling 200+ monitors in Terraform; consolidated a multi-cluster Kubernetes estate into a centralised architecture, reducing operational overhead by 60%; and built multi-tenant Terraform for 20+ automotive OEMs, where Spacelift CI/CD reached 99.9% deploy success and cut manual deployment time by 80%. I've stood up enterprise-grade IaC from scratch — taking deployments from hours to minutes — owned production data infrastructure such as EMQX and ClickHouse through capacity planning and HA tuning, and acted as incident commander on high-severity events, embedding postmortem and on-call practices that cut escalation noise by 35%.

Available for fractional and project engagements: SRE and observability, platform and IaC builds, Kubernetes architecture, incident-readiness reviews and infrastructure migrations.
