There is a question I get asked more often than any technical query: "Why are you still so passionate about mainframe?" After 17+ years, multiple roles, countless migrations, and a growing body of AI-powered innovations built on the Z platform — my answer is always the same. Because the mainframe is not a relic of the past. It is one of the most quietly powerful platforms of the future. And I intend to spend the next chapter of my career proving it.
From DBA to Platform Polymath: My Mainframe Story
My mainframe journey did not follow a linear path — and that is precisely what made it extraordinary. It began over 17 years ago when I stepped into the world as a DB2 DBA. At the time, I had no idea just how deep this platform could go, or how many directions it would take me.
Over the years, I evolved well beyond a single discipline. I took on roles as a DB2 Systems Programmer, Adabas DBA, IMS DBA, Datacom DBA and Systems Programmer. I led high-stakes infrastructure migrations, moving entire mainframe environments from z12 to z15 — complex, precision-driven projects where every decision carries real business consequences. I developed a deep specialisation in performance tuning and later expanded into mainframe performance and capacity management, understanding not just how software behaves, but how hardware breathes.
In recent years, I have taken on perhaps the most exciting frontier of all: building AI-based solutions on the Z platform. What began as curiosity became conviction. The mainframe is not incompatible with the future — it is perfectly positioned for it.
"My career has never been about staying in one lane. It has been about going wide, going deep, and never stopping."
How Becoming an Advocate Quietly Changed Everything
Advocacy is one of those things that looks optional from the outside but feels essential once you are inside it. I did not become a mainframe advocate to build a personal brand or climb a ladder. I became one because I could not stop talking about what I was discovering — and the community responded.
The impact, however, went far beyond what I expected. Here is what advocacy genuinely did for me:
• It connected me with some of the brightest mainframe SMEs on the planet. Not just virtually, but in real conversations, real collaborations and real exchanges of knowledge that pushed my thinking forward in ways no certification or course ever could. The mainframe community, I quickly learned, is one of the most generous and intellectually rich communities in all of enterprise technology.
• It pushed me into territory I might never have explored on my own. Through advocacy — attending sessions, reading thought leadership, engaging in community discourse — I discovered cutting-edge AI tools built for the Z platform: Concert for Z, SMU and BoB. These are not the tools that get the flashy headlines in the mainstream tech press. But for those of us who understand the scale and criticality of mainframe workloads, they represent something genuinely transformative.
• It gave me the confidence and platform to lead AI-driven transitions within my own organisation and community. I moved from consuming innovation to creating it — building solutions, proposing ideas, and influencing how the people around me think about what mainframe can do in a modern enterprise. Most powerfully, it kept me relevant. In a technology landscape that changes by the month, advocacy is what kept me from getting lost.
"I am firmly convinced the mainframe has well over 100 years still ahead of it. Not because it has survived — but because it continues to evolve."
The Moment Everything Clicked: Building the Future on Z
If I had to point to the single moment that crystallised everything I believe about mainframe advocacy, it would be the day I demonstrated an AI-powered solution I had built — and watched the room go quiet.
The project had two components that I was particularly proud of. The first was a Total Cost of Ownership (TCO) management solution for the mainframe — giving organisations a clear, intelligent view of exactly what their mainframe environment costs them and where optimisation opportunities exist. The second was an AI agent capable of answering questions about a mainframe system in natural, conversational language — making the platform accessible in a way that had simply never existed before.
The architecture was both technically rigorous and genuinely modern. I used z/OSMF and Zowe plugins to interface with Java, building a visual dashboard that surfaced insights in an intuitive, consumable format — with data governance built directly into the same interface, not bolted on as an afterthought.
When I showed this to my peers, the reaction was one I will not forget. Surprise. Curiosity. And then, gradually, recognition. Not of the technology — but of a truth they had perhaps not fully internalised before.
"Modernisation does not mean migration. Every tool needed for modern, intelligent, human-friendly interaction already exists within the mainframe ecosystem. We do not need to move away — we need to go deeper."
That insight has become a cornerstone of everything I advocate for. The mainframe does not need to be replaced to be modern. It needs people who understand it deeply enough to unlock what it is already capable of.
What I Am Known For: Depth, Drive, and Delivering Solutions
After 17+ years, I have developed a reputation in the communities and organisations I work with. Not because I sought recognition — but because consistent behaviour, over time, speaks for itself.
• Technical depth that goes all the way down. From SMF log analysis and SVC dump interpretation to WLM parameter tuning and LPAR management — I understand the mainframe not just at the application or database layer, but at the hardware and systems level where performance is truly won or lost. This breadth of understanding, from the silicon to the software, is rare and has repeatedly proven invaluable.
• A relentless, self-directed approach to learning. I have never wasted a single day without learning something new. That is not a boast — it is a discipline I built deliberately, because this platform demands it. The mainframe is vast, and the professionals who remain relevant are the ones who keep moving.
• Being the person who shows up with answers. Whether it is a performance incident at 2am, a complex DBA challenge with no clean precedent, or a blank-canvas brief to explore what AI on Z could look like — I have always been the person who engages with the problem and comes back with a solution. That reputation, built across disciplines and years, is what I am most proud of.
How I Advocate: Writing, Speaking, and the Power of Connection
I have tried many forms of advocacy over the years, but two consistently feel most natural and most impactful to me: writing and speaking.
Writing, in particular, is where I feel most at home as an advocate. It gives me something that real-time conversations rarely do: the space and time to consolidate. Over 17+ years, I have accumulated an enormous breadth of horizontal knowledge — across hardware, performance, databases, systems programming, AI and more. Writing is where all of that converges. It is where I can draw connections between disciplines, synthesise what I have learned, and turn that synthesis into something that moves thinking forward — for me and for the reader.
Speaking at events adds a different dimension. It is the human layer of advocacy — where you see ideas land in real time, where conversations spark spontaneously, and where you connect with people in ways that a blog post, however well-crafted, simply cannot replicate.
But if I am honest about what drives all of it? It is the aspiration to connect with mainframe SMEs from all over the world. To sit across the table — physically or virtually — with people who have dedicated their careers to this platform, to exchange ideas freely, and to walk away with something that makes both of us better at what we do.
"The real value of advocacy is not what you broadcast. It is what you build — the relationships, the ideas, the community that grows around shared passion."
What Keeps Me Excited: A Platform for Expression, Innovation and Relevance
People sometimes assume that after 17+ years in any technology, the excitement must fade. That familiarity dulls the edge. For me, the opposite has happened.
What keeps me engaged with the mainframe — deeply, genuinely engaged — is that it gives me something I value above almost anything else professionally: a platform to express myself. A space where my ideas have room to become real things. Where the depth of my knowledge is an asset rather than an anomaly. Where building an AI agent that makes a mainframe talk back like a human is not a fantasy — it is a project.
It also keeps me building relationships that matter. The mainframe community is, in my experience, unlike any other in enterprise technology. It is characterised by genuine expertise, deep generosity and a shared commitment to something that most of the world underestimates. Those relationships have shaped my career, sharpened my thinking, and kept me grounded through every evolution this platform has gone through.
And perhaps most practically — it keeps me relevant. In a world where careers are built and dismantled by the speed of technological change, the mainframe remains a constant. Not because it stands still — but because it moves with purpose, and there will always be a premium on the people who understand it.
Advice for Future Advocates: What I Would Tell My Younger Self
If you are standing at the edge of the mainframe community, wondering whether to step in — let me offer you the perspective of someone 17 years deep:
• Learn everything. The mainframe is not a narrow specialisation — it is an entire universe of interconnected disciplines. Performance tuning, database architecture, systems programming, capacity management, AI integration — every layer you understand makes every other layer more powerful. Do not limit yourself to one lane. The professionals who do wonders on this platform are the ones who went wide before they went deep.
• Stay relentlessly current. The mainframe evolves constantly — and the gap between those who know what is coming and those who are always catching up is enormous. Make it your business to be the first person in your organisation who knows about the latest IBM enhancement, the newest tooling ecosystem, the most recent community development. Relevance is not a passive state. It is something you actively maintain.
• Network first, network always. I cannot overstate this. The relationships you build in the mainframe community will open doors, shift your perspective, accelerate your growth and sustain your motivation in ways that no technical skill alone ever will. Reach out, engage, contribute, show up. The mainframe community rewards genuine participation with extraordinary generosity.
The mainframe is not a legacy platform waiting to retire. It is a living, breathing, evolving technology — and it belongs firmly in the conversation about the future of enterprise computing, AI, and intelligent infrastructure.
Seventeen years in, I am more convinced of that than ever. And I am just getting started.
