Few enterprise architects started out debugging C code on Unix for warehouse management systems. I did. That path from low-level software engineering to shaping the technology strategy of global organisations is not a detour, it is the point. Enterprise Architecture only works when it bridges both worlds: the technical reality of systems and the business logic of strategy. I've spent decades on both sides of that bridge. I've shipped production code, led SAP rollouts across continents, managed large international teams of internal and external specialists, and built EA frameworks from scratch. I know what happens when the architecture model outpaces what the organisation has the capability to execute, and I know how to close that gap. At Schaeffler, I built EA frameworks from the ground up, served as domain architect across R&D and additive manufacturing, and delivered a full E2E architecture analysis for the Aerospace subsidiary that translated directly into an executive roadmap. My Master's thesis on heterogeneous IT landscapes turned out to be a blueprint for almost every enterprise challenge I've worked on since. At Siemens Healthineers, I define technology roadmaps for the SAP ecosystem, shape the target architecture for supply chain management and warehouse operations, and co-create EA services as structured, consumable assets, so teams get guidance they can actually act on. A major milestone was governing the integrated system design for a large-scale corporate carve-out, with SAP S/4 HANA and Salesforce as the backbone systems. Architecture recommendations earn credibility when they come from someone who has worked close enough to the technology to know where the theory ends and the complexity begins. So I keep building and coding, diving deep into AI-assisted solution design to understand not just what these technologies promise, but what they actually deliver. That practical curiosity is what keeps my architecture thinking honest. I post about the strategic role of architecture in enterprise competitiveness, how technology decisions compound over time, and what separates organisations that execute from those that drift. Because EA only matters if it makes companies run better, compete smarter, and grow. That applies whether you have 50 employees or 50,000.
As Enterprise Architect at Siemens Healthineers, I work at the intersection of business strategy and technical architecture: defining technology roadmaps across the SAP ecosystem, shaping the target architecture for supply chain management and warehouse operations, and ensuring coherence across complex, interdependent programme workstreams. A major milestone was governing the integrated system design for a large-scale corporate carve-out, with SAP S/4 HANA and Salesforce as the core backbone systems. A focus area is co-creating enterprise architecture services as structured, consumable assets, translating EA thinking into guidance that product owners, solution architects, and programme leads can actually use, rather than documents that sit on a shelf. Staying close to the technology through hands-on coding and AI-assisted solution design, ensuring that architectural recommendations are grounded in what emerging technologies actually deliver, not just what they promise.
Built a comprehensive application and project portfolio spanning the full operations domain (purchasing, production, and logistics), giving the business its first coherent view of what ran where, what it cost, and what it needed to become. Led strategic alignment workshops with business and IT stakeholders at divisional and regional level, surfacing capability gaps, translating business drivers into project requirements, and creating roadmaps that connected operational reality to long-term transformation goals. Defined the factory stack architecture as part of Schaeffler's SAP S/4 HANA initiative, a pivotal contribution to one of the largest ERP transformations in the company's history.
Extended Schaeffler's EA framework into the data domain and developed solution design guidelines to ensure coherence across the portfolio and reusability of architecture building blocks and patterns. Acted as domain architect for R&D, shaping the target EA landscape for product development in close alignment with business and IT stakeholders. Designed the end-to-end solution landscape for the additive manufacturing department, with the explicit goal of scaling from pilot to full production processes. Conducted a full E2E architecture analysis for the Schaeffler Aerospace subsidiary, delivering a structured roadmap of quick wins, alignment needs, and proposed strategic projects. An example of how architecture work translates directly into executive decision-making.
Led architecture activities across Schaeffler's IT units and coordinated a distributed team of domain architects, setting direction, aligning methods, and ensuring that architecture practice translated into real outcomes on the ground. Implemented TOGAF and ArchiMate as the standard frameworks for architecture management and transformation projects, aligning modelling approaches with the process and organisation development department. Consulted project leads on software and system architecture decisions and served as the internal contact for IT security and data privacy matters. Ensured tight alignment between architecture practice and IT portfolio governance, connecting architectural decisions to the product and project portfolio that funded them.
