Top SchoolFilip Hajný is a Senior Systems Engineer with 21 years of experience designing and operating cloud and hybrid infrastructure from startup to enterprise scale, currently based in Prague. He specializes in infrastructure as code, CI/CD, container orchestration and multi-cloud deployments (AWS, GCP, Azure and on-prem), and routinely uses tools like Terraform, Ansible, Kubernetes, Docker and Helm. As a self-employed consultant and former Joyent engineer, he combines deep platform-level troubleshooting with pragmatic architecture and clear handover documentation that keeps customers and teams aligned. He also mentors DevOps teams and applies AI/GenAI tooling where it adds value, bringing a measured balance of automation and operational resiliency.
