En charge de la modernisation du SI Candriam par la mise en place d'Azure APIM à l'échelle globale (New-York Life Investments, Luxembourg, Bruxelles,...). Développement (.Net 8) et mise en place de l’initiative composée d’une gouvernance duale (projets/architecture), d’un accélérateur technique permettant la production d’API (FullRest/OData/GraphQL) et d’une infrastructure hybride (Azure/OnPrem) via Azure APIM. L’ensemble s’intègre dans un CI/CD avec l’Azure DevOps de la société. Le système est connecté à la première IA de l’entreprise. Objectifs : - Rendre le métier 'Programmable' par la voie des APIs, - Moderniser les applicatifs vers la voie des EDA (Event Driven Architecture), - Favoriser l'interopérabilités entre métiers et partenaires, - Fournir de nouvelles sources pour les agents d'IAs génératives spécifiques aux métiers, - Réduire l'obsolescence technique (ex SOA, WCF). Méthodes : - Domain Driven Design & Domain Driven Architecture, - Micro Services, - Hexagonal Architecture, - Event Driven Architecture. En parallèle, je conseille et anime les Comité de revue d’architecture au sein de la cellule d’architecte de Candriam/New York Life.

Au sein du « Lab Innovation Center » de la Banque de France, j’opère en tant qu’« Architecte des Innovations ». Mon rôle consiste à opérer à des échelles différentes qui mettent en œuvre mes capacités d’architectures acquises au cours de mes 20 dernières années en tant qu’architecte (Technique, Applicatif, d’entreprise, de domaine) afin de gérer le portefeuille des expérimentations et innovations de la Banque de France.

TravelStore Web Site: Complete re-design of a third of the site for the entire hotel’s subsystem (see www.travelstore.com/hotels), including full development cycle. I designed the architecture from the beginning using the latest techniques such as persistence management, load balancing, and states objects management. My work was deployed on the client’s live site very recently. Thousands of users browse the site and book their hotels. I worked closely with travel experts to make the necessary business objects. I adapted all my objects to be stateless, MTS compliant and MSMQ compatible. I specifically paid attention to the stability and robustness of my components, since this set of components was designed to work without any maintenance and this, twenty-four hours a day. In order to make this project a success, I leaded and trained other web developers to use this engine and maintain the different Web pages to constantly offer new functionalities throughout the site.
