Z/SPRESSO is more than a blog, it’s a tribute to a lifelong passion for Mainframes and the legendary Z world.
It all began in 2008, when I joined IBM as a Mainframe Operator. Since then, I’ve spent 17 years immersed in the systems that quietly power the backbone of global infrastructure. From late-night troubleshooting to deep dives into IBM releases, this journey has shaped not just my career, but my identity.
Z/SPRESSO is my way of finally sharing that experience.
Whether you’re a seasoned tech professional, a curious student, or a client wondering what’s behind the systems you rely on—this space is for you. Expect everything from practical tips (like Display Commands) to reflections on the evolution of Z, and conversations that make complex topics feel approachable.
My goal is simple: To demystify Mainframes. To connect with fellow Z passionate. And to prove that these systems aren’t relics—they’re resilient, relevant, and very much alive.
So grab a virtual espresso, settle in, and let’s explore the legacy that keeps on running.
