About me
Intro
Lead Platform Engineer / Cloud Infrastructure Consultant with 10+ years in Cloud/DevOps and 18+ years in infrastructure and security engineering. I specialize in designing and operating scalable cloud platforms using AWS, Kubernetes, and Infrastructure as Code (Terraform), supporting production systems and engineering teams at scale. My focus is on building reliable, automated infrastructure that enables teams to ship faster while maintaining high availability and performance. Key areas of expertise: • Kubernetes platform design (EKS, AKS, GKE) • Infrastructure as Code & GitOps (Terraform, ArgoCD, CI/CD) • Cloud architecture across AWS / multi-cloud environments • Observability, reliability, and incident response • Secure and scalable networking across cloud and on-prem systems • Cloud cost optimization and infrastructure scaling Throughout my career, I’ve worked on high-scale systems, global platforms, and complex infrastructure environments, contributing to both hands-on engineering and technical leadership. I’m particularly interested in: • Platform engineering & internal developer platforms • Cloud Infrastructure and Security engineering • Distributed teams solving complex infrastructure challenges Open to remote opportunities (EU/UK / global async teams).
