Hi, I’m Rui Miguel Feio.
I’m a technology leader, cybersecurity advocate, international speaker and lifelong believer that great technology is ultimately about people.
For more than 25 years I’ve helped some of the world’s largest organisations secure, modernise and get the very best from their mainframe environments. My career has taken me across banking, insurance, government, healthcare, retail, logistics and many other industries where reliability, security and resilience simply aren’t optional—they’re business critical.
Today I lead international mainframe consulting and services teams at BMC, helping customers solve complex technical and business challenges while preparing for the next generation of enterprise computing. My passion lies at the intersection of mainframe technology, cybersecurity, enterprise architecture and AI-driven transformation.
But my work doesn’t stop with customers.
I’m passionate about sharing knowledge and helping others grow. I’ve delivered technical training, spoken at conferences across Europe, authored hundreds of technical articles, and co-authored the IBM Redbook ABCs of z/OS System Programming Volume 6. I also chair the GSUK Security Working Group, bringing together security professionals, system programmers, auditors and technology leaders to advance best practices across the mainframe community. More recently, I co-founded Mainframe Society, a global community dedicated to connecting, supporting and inspiring mainframe professionals around the world.
One of the things I enjoy most is making complex subjects accessible. Whether I’m presenting to an audience of hundreds, mentoring engineers, or writing technical content, my goal is always the same: turn complicated ideas into practical knowledge people can actually use.
Outside of work you’ll usually find me writing, speaking, exploring emerging technologies, following the ever-changing cybersecurity landscape, or discovering yet another gadget that promises to make life easier (they rarely do).
Technology never stands still, and neither do I.
If you’re interested in enterprise technology, cybersecurity, mainframes, leadership, or simply enjoy exchanging ideas with curious people, I’d love to connect.
