Redesign of FDJ's IS, initially in PHP 10 years ago. Transition to Nodejs for the entire architecture. I worked on 4 services: A worker responsible for consuming through an XML format all the odds calculated by traders. This data is then processed, mapped according to business rules, and stored in a MongoDB database using an ExpressJS service to finally be made available as an SQLite database for FDJ's mobile apps. A service exposing the same data in Rest for web applications through an ExpressJs application. A BFF (back for front) service intended to make all this data public for the entire FDJ ecosystem. A CMS developed in ExpressJS / Angular allowing contribution of other editorial information added by contributors. All these applications/services are developed in NodeJS / TypeScript / ExpressJs with a "clean archi" code architecture (models, repositories, dto, services, decoupling), unit tests, and dependency injections. All deployed on a docker / jenkins / gitlab CI factory. Workflow implemented: Scrum methodology, Git rebase strategy, merge requests, and code coverage check. Team of 4 Fullstack people + an architect.
