Summary
🤩
Rockstar🎓
Top SchoolSteven Horsman is a Senior Software Engineer at IBM with eight years of focused experience in open-source and cloud-native projects, and a broader 15+ year IBM tenure building mainframe-integrated tooling. He is a core contributor and Kata Containers Architecture Committee member who helped pioneer Confidential Containers, improving build, CI/CD and deployment automation to make VM-like container isolation practical on OpenShift. Steven led the technical design and delivery of multiple IBM initiatives—most notably Zowe and IBM Z Operational Insights—creating production-ready CI/CD pipelines, REST services and full-stack architectures. He combines deep mainframe domain knowledge with hands-on DevOps skills (shell scripting, pipeline automation, Kubernetes integration) and a track record of chairing cross-project architecture and community meetings. Based in Winchester, UK, he brings both leadership and execution: starting projects, creating repos and pipelines, and driving releases end-to-end. An early adopter of confidential computing patterns, he quietly bridges legacy mainframe ecosystems and modern open-source cloud infrastructure.
