Hello, world! I'm
Jiří Pomazal
Principal Infrastructure Engineer with 15+ years in the field. I design and run reliable, scalable, container-first platforms — from bare-metal servers to multi-cloud OpenShift clusters. Currently pushing the limits of containerized LLMs in my spare time.
Prague, Czechia
Services & Expertise
Platform Engineering
Design and administration of OpenShift v4 & Kubernetes clusters in on-prem and multi-cloud environments (VMware, Azure ARO). Lifecycle management, capacity planning and cluster hardening.
GitOps & CI/CD
End-to-end delivery pipelines using ArgoCD, Red Hat ACM, Tekton, Jenkins and GitHub Actions. GitOps principles applied at enterprise scale across hundreds of applications and environments.
DevSecOps
Security-first application delivery: container image scanning, policy enforcement, secrets management and full CI/CD pipelines with Artifactory, Docker/Podman, and automated compliance checks.
Observability
Designing E2E cloud observability stacks built on OpenTelemetry and Prometheus. Experience with ELK, Zabbix, AppDynamics and Grafana for monitoring, alerting and deep performance analysis.
Linux & Hosting
15+ years of Linux server administration (RHEL, Debian, Fedora). Running webhosting, mail platforms, DNS, and serverhosting services since 2011 through ZIKUM, s.r.o.
Identity & IAM
Service ownership and administration of Identity Management applications based on SAML, OAuth and OpenID Connect protocols in large enterprise banking environments (Česká spořitelna).

Life Beyond the Terminal
Homelab & Self-Hosting
Running a personal homelab with KVM/Docker, self-hosted services (GitLab, BackupPC, Harbor) and constantly experimenting with new open-source tools. If it can run in a container, it probably already does.
Local LLMs & AI Tinkering
Exploring the world of containerized large language models with Ollama and custom inference stacks. Figuring out how to squeeze GPU-accelerated inference out of consumer hardware in WSL2 environments.
Gaming
A fan of strategy and simulation titles — the kind of games where you're essentially running infrastructure anyway, just with better graphics. Occasional retro gaming on the side.
Cycling & Outdoors
Balancing screen time with time outside. Road cycling around Prague and the Czech countryside is the best way to reboot the brain after a long week of debugging cluster issues.
Photography
Capturing urban landscapes, architecture and street life. Prague is an endlessly photogenic city — there's always something new to frame.
Tech Reading & Learning
Keeping up with the fast-moving cloud-native ecosystem. Reading release notes, CNCF blog posts, and the occasional deep-dive into kernel internals when something breaks in a fascinating way.
