Summary
👤
Senior🎓
Top SchoolStephen Johnson is a DevOps Engineering Lead with 14+ years building and leading platform teams to deliver secure, cost‑efficient cloud infrastructure across startups and enterprises. He has driven major migrations and optimisations—moving platforms from Heroku to AWS, shifting workloads from EC2 to serverless and EKS, and cutting cloud spend by ~30% through right‑sizing and enterprise discounts. Comfortable hands‑on with Terraform, Kubernetes, ECS, Lambda, Puppet and Docker, he pairs deep systems and networking foundations (RHEL, Solaris, Cisco) with people leadership and audit experience (SOC2/security reviews). Stephen has repeatedly led small teams to scale machine‑learning and analytics workloads using spot fleets and large batch processing, showing a knack for pragmatic cost engineering. Based in Wales, he’s equally at home in technical trenches or setting quarterly targets and career plans, and often surfaces non‑obvious gains by aligning global and region‑specific infrastructures (e.g., China) to central stacks.
