Martin Baránek

DevOps & Linux Engineer building AI-powered tools · Brno, CZ 🇨🇿 · currently team.blue

I build reliable infrastructure, automation, and practical AI tooling. My work connects Linux and cloud operations with coding agents, RAG, MCP servers, and local-first developer tools. I am also starting to explore robotics with ROS 2.

🤖 AI, developer tooling & robotics

I use AI as an engineering tool rather than a substitute for verification: grounding outputs in real data, browser evidence, repeatable checks, and human-readable reports. I stay model-agnostic and experiment with both Western and Chinese models, cloud APIs, and local inference.
