Summary
🤩
Rockstar🎓
Top SchoolAlessandro Di Stefano is a Senior Software Quality Engineer with a PhD and a decade of experience building cloud-native, multi-architecture systems and CI/CD pipelines, currently leading OpenShift arm64 and multi-arch compute enablement at Red Hat in London. He blends deep research grounding with hands-on engineering—porting upstream and downstream QE suites, automating CI for AWS, Azure and bare-metal, and designing networked test infrastructure for ephemeral on-prem clusters. An active Open Source contributor to OKD and OpenShift projects, he has materially improved release tooling and verification tests, including arm64 support and bare-metal IPI enablement. Past roles span GKE migrations, microservices redesigns, and low-level systems work, reflecting comfort across Linux, Kubernetes/OpenShift, Go, and automation tooling. Unusually for an engineer at his level, he pairs this systems expertise with musical training and concurrent-systems research from his PhD, giving him a distinctive mix of technical rigor and creative problem-solving.
