I build resilient AWS platforms and practical AI solutions.
I’m a platform and DevOps engineer based in Brno, maintaining a shared platform for multiple applications across dozens of AWS accounts. My sweet spot sits where software engineering, cloud architecture, and developer experience overlap.
I focus on infrastructure as code, GitHub CI/CD workflows, FinOps, and observability, using Pulumi, TypeScript, and Datadog across serverless and container platforms on AWS.
I’ve been a Platform Engineer at Purple Technology since March 2025, after previously working there as a Full Stack Serverless Developer.
I’m also a core member of Purple Technology’s AI initiative, helping teams adopt AI across the company and implementing agentic solutions with Claude, Codex, n8n, and AWS Bedrock.
