Rockstar🎓
Top SchoolJose Arza is a QA Engineer and SDET with 9 years of experience building reliable CI/CD, testing and observability tooling for cloud-native systems. He has driven quality and automation at Weaviate—creating a Kubernetes-based testing environment, an end-to-end test framework, and a CLI for data ops—and previously led Windows containers QA and multi-cloud test automation at Red Hat for OpenShift. His background blends hands-on DevOps (Terraform, Ansible, Helm), Go test development, and scripting across Bash, PowerShell and Python, with practical experience enabling Windows worker support and multi-architecture Docker workflows in major open-source projects. Jose is a frequent contributor to high-profile repos such as Weaviate and OpenShift release tooling, where he improved cluster automation and CI for Windows and multi-arch builds. Based in Madrid, he combines deep systems-level knowledge from telecom and cloud domains (Ericsson, OpenStack TripleO) with a strong operational focus on reproducibility and on-call support. Colleagues rely on him as a Kubernetes install and testing reference who turns complex deployment challenges into repeatable automation.
