Description

Leveraging a dual expertise in Software Architecture and Product Strategy, I help organizations translate complex business needs into robust technical solutions.

🚀 Technical Leadership & Product Vision (CTO)

From Vision to Execution: At Astrastellar, I led the strategy for a multi-product ecosystem. I designed an EduTech platform (SaaS) on a modern stack (Next.js 14, Clean Architecture) while ensuring hands-on delivery.
Strategic Framing (DDD): For the LegalTech branch, I orchestrated the design phase using Domain-Driven Design. I use EventStorming and User Story Mapping to perfectly align technical modeling (Bounded Contexts, CQRS) with legal requirements.

🏗 Architectural Excellence & Modernization

Software Craftsmanship: I transform technical debt into a competitive advantage. I led the migration of legacy systems to Modular Monoliths and hexagonal architectures, ensuring testability and maintainability.
Performance & Sustainability: At AXA, I led critical Green IT and optimization initiatives (Core Web Vitals), proving that technical performance and digital responsibility go hand in hand.

🌐 IS Urbanism & Global Scale

Complexity Management (M&A): My experience at EssilorLuxottica involved pure IS Urbanism: defining integration strategy for a global merger, rationalizing APIs across 680 entities, and governance via Google Apigee.
International: Culturally adaptable, I am ready to drive technical excellence in demanding hubs like Switzerland and the UAE/Qatar.

Key Technical Expertise:

Architecture: Domain-Driven Design (DDD), Enterprise Architecture, Clean Architecture (Hexagonal), Modular Monolith.
Stack: Next.js 14 (App Router), TypeScript, React, Node.js, PostgreSQL, Docker/OpenShift.
Method: EventStorming, Agile/Scrum, RICE Scoring, CI/CD, Lean Management.
