HATEM GHABRI

– Leading enterprise architecture governance across a multi-domain portfolio (30+ initiatives) impacting mission-critical financial flows and core operational processes across multiple business units. – Defined domain-level target architectures and structured transition strategies for legacy systems modernization within large-scale multi-year enterprise transformation programs, aligning IT evolution with business and risk priorities. – Led strategic refactoring initiatives on consumption and volume projection engines, reducing structural technical debt through phased decomposition. – Presented and defended architectural decisions in monthly Architecture Review Boards (ARB) in coordination with CIO and governance bodies. – Structured formal escalation processes and architecture exception frameworks. – Conducted cross-domain arbitrations balancing delivery constraints, regulatory compliance and long-term scalability. – Influenced strategic portfolio-level architectural decisions in coordination with executive stakeholders.

– Large-scale transformation across a multi-country enterprise environment within a digital banking modernization program. – Defined target architectures and incremental modernization roadmaps across multiple transformation streams. – Orchestrated exposure of legacy pricing monoliths through API-based architecture, enabling phased ecosystem integration while preserving legacy core stability and ensuring controlled decoupling of critical business capabilities. – Enabled end-to-end digital leasing journeys (white-label integration with automotive manufacturers). – Structured cross-domain architecture consistency across open banking and digital platforms. – Presented architecture dossiers to Design Authority and governance committees. – Contributed to enterprise Cloud and Data transformation strategy.

– Banking risk and regulatory transformation within a highly regulated banking group environment. – Defined target architecture and transition roadmap for modernization of legacy risk engines (default & rating models) within a structured transformation program, directly impacting regulatory reporting capabilities under ECB constraints, including phased migration strategy, coexistence model and controlled decommissioning of legacy components. – Structured progressive refactoring toward microservices and event-driven architecture, improving maintainability and scalability of core risk calculation systems. – Presented domain-level transformation roadmaps to architecture governance committees. – Aligned regulatory constraints with scalable architectural design. – Contributed to API governance and system urbanization strategy.

– Led progressive modernization of legacy contribution and P&L engines within business-critical, low-latency electronic trading environments, ensuring performance stability and operational resilience during architectural transition. – Designed scalable trading architectures and automated risk processes aligned with desk performance constraints. – Balanced performance, resilience and control requirements in high-stakes trading environments. – Contributed to cross-stream architectural decisions impacting desk-level performance and risk governance.

– Contributed to modernization of legacy electronic trading engines within high-performance, low-latency environments supporting mission-critical financial flows across multi-asset platforms. – Designed high-performance pricing systems in latency-sensitive environments. – Supported migration toward scalable electronic trading platforms.
