Senior🎓
Top SchoolRay Walker is a lead analytics application engineer with 12 years of experience building cloud-native data platforms and AI-enabled solutions, currently leading analytics engineering at Bain & Company from Tasmania. He combines hands-on infrastructure and application engineering—spanning serverless, Kubernetes, Terraform/Terragrunt, Python and React—with product-minded platform architecture for healthcare and non-profit domains where privacy, compliance and event-driven design matter. Previously he led Greenpeace’s serverless data platform and architected a global healthcare ingestion and governance product at Max Kelsen, integrating FHIR, DICOMweb and Vertex AI into secure, continuously delivered pipelines. A serial autodidact who enjoys “throwing things at clouds,” Ray brings practical DevOps craftsmanship and fast-feedback security tooling to distributed teams while still maintaining a legacy hosting practice that keeps him grounded in operations.
