I'm a platform engineer and tinkerer from Prague, working across cloud and AI.
A Python CLI that simulates SCP, IAM & RCP policy changes against real CloudTrail data - so you can safely validate permission changes across a multi-account org before they ever hit production.
A personal cluster running real production patterns: GitOps with Flux CD, Kustomize for environments, and SOPS + Age secrets committed safely to Git. Exposed via Cloudflare Tunnel - no public IP, no open ports, zero-trust by default.
A gamified habit tracker with real RPG mechanics - XP, levels, quests. Built end-to-end.
Besides my two highly productive cat companions, my third companion is Claude Code: custom subagents that handle the repetitive parts of the job, plus skills and MCP servers wired into my workflows. I'm always re-tuning the setup as the tooling shifts. Always happy to talk about AI and other workflows.
I used to write - life, engineering, cloud, business, whatever was in my head. These days I'm mostly on a padel court.
How I fought back against digital distraction - a curated content system and a bit of JOMO.

Consultant. Built production chatbots and voicebots in Python, then GenAI assistants for EMEA Audit & Legal teams. Shipped cloud-native contact-centre (CCaaS) architectures.
Cloud AI Engineer. Owned an enterprise AI orchestration platform on Azure Machine Learning for automated content generation - with security gates and guardrails for safe model deployment, plus automated PR environments to spin up QA instances on demand.
Platform Engineer. Defined the multi-cloud identity standard across 80+ AWS accounts and 150+ Azure subscriptions, and built an automated identity-governance platform that wiped out 100% of manual provisioning.
I'm Radek - a platform engineer with 7+ years in IT, four of them building secure cloud infrastructure, identity systems and AI-powered tooling across clouds. I care about infrastructure as code, automation, and self-service platforms that take the operational load off engineering teams.
I started on the service desk, where I learned to build for the customer. And I still do - that's what all of it is about.
If that resonates with you, grab a coffee or tea and let's talk
