International Technical Leadership: Orchestrated architecture workshops across 8 European & APAC regions, bridging the gap between evolving business requirements and technical feasibility to ensure predictable delivery cycles across distributed teams. Critical Payment Infrastructure: Directed the architectural integration of Adyen Checkout API, replacing legacy systems with a secure, scalable solution. Acted as the escalation point for complex transaction issues, guaranteeing operational continuity for Rexel’s high-volume digital sales. Architecture Standardization: Formalized design patterns and produced detailed technical blueprints for complex features. This initiative aligned development squads, eliminated ambiguity, and prevented technical debt in early phases. Omnichannel Reliability: Engineered robust mobile-to-web data flows and hardened Order Management workflows. This re-architecture resolved persistent data inconsistencies, significantly improving system stability and trust in customer-facing data (order history/tracking). ESG & Data Modeling: Enabled Rexel’s sustainability roadmap by designing the data model for Environmental Product Labeling (A–E scores), ensuring seamless propagation of environmental data across the entire digital ecosystem. DAM Content Enablement: Extended the existing Amplience integration within SAP Commerce/Hybris to support technical product assets (PDFs, documentation, datasheets) directly on PDPs.

Digital Tax Transformation: Leveraged the SAP Hybris Public Sector accelerator to modernize the regional tax portal, enabling secure digital services for Brussels' citizens and businesses. Resilience & Performance: Designed and executed critical load testing strategies (Gatling) to validate platform robustness, ensuring stability during high-traffic fiscal declaration periods. Complex Workflow Integration: Architected the integration of Orbeon Forms with Hybris, digitizing sensitive tax processes (consulting notices, payments, claims, document uploads) into secure, seamless workflows. Technical Advisory: Authored technical specifications and provided strategic estimates, advising stakeholders on the best trade-offs between implementation speed ("quick-wins") and long-term architectural quality.

Global E-commerce Leadership at Yves-Rocher : Led the technical evolution of the international B2C platform spanning 7+ strategic markets (FR, DE, RU, etc.), ensuring architectural consistency across web and mobile channels. Marketing Enablement & CMS: Architected a scalable Multi-Country Campaign Management module and customized SmartEdit, empowering local business teams to autonomously manage promotions and content, significantly reducing Time-to-Market. Conversion & Personalization: Spearheaded the integration of AI-driven personalization engines (Target2Sell, Kameleoon) and revamped Solr search architecture (indexing, boosting rules). These optimizations directly enhanced product discoverability and user engagement. Data & SEO Strategy: Designed a robust Data Layer and integrated GTM to improve analytics accuracy, while implementing structured data standards to boost SEO ranking and organic traffic. Core Transactions & Security: Secured critical checkout flows through Payline integration and resolved high-impact catalog synchronization issues, ensuring data integrity and stability across all country storefronts.

Technical Delivery Leadership: Led development squads (on-site & offshore) for major retail clients (GrandVision/Apollo, Camaïeu), ensuring code quality reviews and successful production go-lives (e.g., Camaïeu FR/PL launch). OMS & Supply Chain Logic: Designed and implemented complex Order Management workflows (payment, returns, refunds) and engineered dynamic delivery date algorithms factoring in multi-supplier constraints and non-working days. DevOps & Security: Acted as Release Manager, driving end-to-end deployment strategies. Hardened platform security by implementing robust protections against web vulnerabilities (XSS, CSRF), ensuring compliance and resilience. Business Logic Customization: Translated complex functional requirements into scalable Hybris solutions, specifically regarding promotion engines and checkout business rules.
