Four decades of turning hard technology problems into clear decisions
I spent more than forty years inside one organisation, moving from the machine room to the boardroom — from programmer in the early days of business computing to Chief Information Officer (CIO) and Chief Information Security Officer (CISO). That executive chapter has now closed, by my own choosing. I have begun a new one as an independent advisor, placing my experience — and my independence — at the service of other companies.

From the machine room to the boardroom
I began as a programmer when business computing still meant mainframes and punched discipline. That start shaped how I work: efficient system design and practical problem-solving, learned hands-on rather than from a framework. One early example was an algorithm I designed, One Ticket One Bit, built to handle meal-voucher processing at scale — a small idea that solved a real operational constraint. In the 1990s I led a different kind of shift: the arrival of microcomputing across the organisation, the retirement of the proprietary mainframes, and the move to open systems — a change in architecture that was also a change in mindset.
As my responsibilities grew, so did the stakes. I led the organisation through the transitions that defined a generation of corporate IT: the Year 2000 problem, the changeover to the Euro, and the full-scale renewal of the ERP estate. These were not technical exercises — they were business-continuity decisions where the cost of error was measured in operations stopped and trust lost.
The executive years
As CIO and later CISO, my work was to make technology a dependable instrument of the group’s strategy — advancing new capability while holding the line on governance and control.
Those years marked the modernisation of the organisation: ISO/IEC 20000 and ISO/IEC 27001 certifications; the continuity effort that kept the workforce operating securely from home during the COVID-19 pandemic; and a digital transformation built on SAP S/4HANA, Salesforce and the Activate AI programme. Leading through a major IT crisis along the way taught me what foresight and steady execution are actually worth when systems are under pressure.
Recognition in the SAP community
Beyond my executive roles, I have contributed to the wider SAP community in Portugal. I served as President of the Board of GUSP — the Portuguese SAP Users Group — representing the interests of SAP-using organisations nationally.
I was also a jury member for the SAP Quality Awards Iberia in 2015, 2017 and 2018, evaluating enterprise SAP projects in the Innovation and Business Transformation categories.
Today: independent advisory
Through LuisFerreira Consulting OÜ, I now apply that judgement to companies facing technological change of their own. My focus spans ERP and CRM strategy, cybersecurity and governance, and IT modernisation — four decades of applied leadership turned into pragmatic, independent advice.
