👤
SeniorJuraj Seffer is a pragmatic DevOps engineer with over a decade of hands-on experience building and automating cloud-native infrastructure across UK fintech, healthcare and SaaS companies. He specialises in Kubernetes-centric platforms, multi-account AWS automation with Terraform/Boto, and CI/CD pipelines (GitHub Actions, CircleCI, Jenkins) that improve speed, reliability and cost-efficiency. Juraj has delivered secure, auditable systems for sensitive environments—from pathogen sequencing at Congenica to air-gapped OpenShift at the Bank of England—often adding customised tooling like self-hosted GitHub runners and SBOM/image-scan pipelines.

Based in Burgas, Bulgaria, he brings a track record of translating strict compliance and security requirements into practical, automated operations.
