Top SchoolZdeněk Jonáš is a Senior Test Lead with 10+ years of experience building resilient QA and DevOps infrastructures for Java-based enterprise systems. He combines hands-on Java engineering with end-to-end test strategy, having architected automated suites, CI/CD pipelines and release processes that drastically shorten build and feedback cycles. At MicroStream and Cyrock.AI he drove test automation, containerized deployments and performance-focused release management using technologies like Maven, Jenkins, GitHub Actions, Docker and Kubernetes. His background includes leading QA teams, designing custom tooling (including a metrics Maven plugin and visualization server) and contributing as an Eclipse Committer to open-source storage work. Equally comfortable writing integration and performance tests as he is orchestrating complex releases, he brings a pragmatic, performance-first mindset to scalability and stability challenges. Based in Bavaria, he pairs deep technical craft with a track record of reducing time-to-feedback from minutes to seconds.
