In the high-stakes world of financial technology, John Dimitropoulos has built a reputation not just as a business leader, but as a quiet force of transformation.
As the Founder and CEO of Liberty IT Consulting Group, John has been instrumental in delivering strategic solutions to some of the nation’s largest institutions.
With over 30 years of experience across corporate technology, consulting, and executive leadership, John has led multi-million-dollar transformation programs for major banks including CBA, Macquarie and Westpac.
“Commonwealth Bank is Australia’s largest company by market capitalisation,” he says. “As an executive manager at the bank at the time, we took accountability for modernising its aging technology and upgraded their systems, introduced digital solutions and simplified bank processes to make the bank first in customer experience and Australia’s leading firm in financial technology. That AU$1.5 billion project that kept 2,500 people busy for five years is by far my most proud career accomplishment.”
Founded on the principle of filotimo, Liberty IT is known for its integrity, agility and depth — qualities that have made it a go-to for institutions navigating complex system overhauls.
“Our mantra has always been to place our customers’ best interests ahead of our own financial objectives,” John explains. “We have a true passion for using technology to improve human experience — at least in our domain, which is financial services.”
John is passionate about redefining the meaning of digital transformation. “Up until two decades ago, technology teams were often considered ‘order takers’ to business divisions within corporations. The business led and technology followed. In 2025, it is evident that technology is not only paramount to businesses, but it is influencing humankind evolution.”
Today, Liberty IT continues to grow with bold vision — one that John hopes will help put Australian consulting firms on the world stage.
“Australia still does not have a management consulting firm in the world’s top 100 largest firms,” he notes. “It’s about time Australian companies rose up to the challenge, embraced technological advancement like AI and boldly competed in the global scene — particularly in financial services.”
But behind the commercial success is a man deeply connected to his roots.
In recent years, John has become increasingly active in Australia’s Greek community, channeling his personal pride in Hellenic culture into meaningful initiatives. Most recently, he hosted the highly anticipated ‘Night with Greek Football Legends’ at Sydney’s Olympus Taverna — an unforgettable evening marking the 20th anniversary of Greece’s Euro 2004 triumph.
“It was an evening full of emotions. We were hosting three modern-day Greek sporting legends… it’s the epitome of the underdog story. One that resonates with me and inspires me daily…” he says.
He credits his parents for instilling the values that now shape both his life and work. “The standout value that I was taught at a young age and watched my parents live by every day is the value of filotimo. It is the value that is at the heart of who I am as a person and the value that my business has adopted.”
John also credits his wife and two kids for standing by him and supporting his career. “None of this would have been possible without the unwavering support of my family,” he says.
Proud of his Greek heritage and thankful for the life Australia has given him, John sees himself as a bridge between the two. “We are fortunate to have adopted the best elements from both countries. Australia is home and the birthplace of my children so my bond with Australia will never be broken.”
In addition to his work at Liberty IT, John supports several charities like the Neil Evans Melanoma Foundation and St. Canice’s Kitchen for those in need and continues to support the efforts of the Greek Consulate in Sydney in any way he can.
As a technology thought leader, he hopes to see greater collaboration between Australia and Greece in the tech space. “I dream of Greek and Australian governments doing more to leverage our excellent diplomatic relations and shared values to co-innovate on technology matters such as digital government, customer service, tax, health and education.”
When asked what advice he would give younger professionals, particularly those of Hellenic background, his answer is simple and powerful: “Anything is possible if you set your mind to it. I hardly spoke a word of English at the age of 16 but through hard work, focus and perseverance the results came.”
Whether in business or community, John leads with quiet determination, cultural pride and an steadfast belief in the power of vision. As Liberty IT continues to scale, so too does John’s commitment to building legacy — not just in systems, but in people.
