🤩
RockstarTomáš Karásek is a freelance software engineer based in Brno with roughly two decades in IT and 13 years of focused professional experience delivering backend systems, DevOps automation and data processing.

His background includes SRE and DevOps roles at CERN and an internship at Google, plus contractor work for companies like Basho, Rovio and Equinix, which demonstrates comfort in both research and production environments. He has contributed to high-profile open-source projects such as Prometheus Alertmanager (Flowdock notifications) and helped simplify Docker-based workflows for a crypto trading robot, showing attention to operational developer experience. Since going freelance in 2015 he has focused on contract work combining Golang/Python development with DevOps delivery, often implementing dynamic inventory, cloud-provider modules and CI-friendly tooling. Colleagues would call him a pragmatic engineer who prefers clear automation and developer-friendly operations over flashy one-offs.
