SKILLS
ABOUT DAVE HORNBY
Lead Automation Engineer specialising in enterprise-scale platform automation and self-service cloud delivery.I build automation frameworks that replace manual infrastructure operations with policy-driven workflows - focusing on reliability, governance, and developer-style platform delivery.My focus is enterprise platform automation: transforming traditional VMware operations into automation-first internal platforms that enable secure self-service, consistency, and operational resilience.My core stack includes VMware Cloud Foundation (VCF), VMware Aria Automation & Aria Orchestrator (formerly vRA/vRO), PowerCLI/PowerShell, vSphere, and CI/CD tooling. I design self-service delivery aligned with platform engineering and automation-first delivery principles — using guardrails such as RBAC, approvals, quotas, and clean JSON contracts integrated with DNS, CMDB, ITSM, and end-to-end observability.Highlights:• ESXi patch automation at scale (10k+ hosts): Aria Orchestrator + PowerShell integrated with vROps, ServiceNow, and HashiCorp Vault → reduced patch cycles by 70%, manual effort by 95%, and removed privileged interactive access.• Day-2 automation: Automated CR/IN validation, pre-checks, and Splunk logging to create consistent audit trails and enforce least-privilege design.• SRE for ESXi: Automated evacuation of unstable hypervisors via vROps/vCenter APIs → protecting ~20 VMs per day from disruption.• Delivered secure, customer-driven blueprints and provisioning workflows used in enterprise internal cloud platforms.I enjoy turning complex runbooks into guard-railed automation pipelines — and measuring the operational impact.
