As a Tech Lead and Senior Lead Developer for Accor Meetings & Events, a major player in the hospitality and hotel industry, I was involved in the launch of a strategic new project by defining the microservices architecture and establishing the technical foundations of the platform. Within a mid-sized team, I designed and developed several services using Node.js and NestJS, following an event-driven approach. I also contributed to building robust APIs and implemented a search engine based on OpenSearch, ensuring the scalability and performance of the system.

As a Tech Lead and Senior Developer within a team for OCP, a leading pharmaceutical distributor, I contributed to the design and development of the integration of a B2B marketplace into the existing application using the Mirakl platform. I brought technical expertise to ensure interoperability with internal systems, while guiding architectural decisions and implementing an efficient search system based on ElasticSearch.

I am aiding Accor in their modernization journey of their B2B solution. By breaking apart their existing Magento monolith into a set of microservices. Utilizing the Magento GraphQl API in this Headless transformation, we are providing Accor’s customers a new, modernized FrontEnd that meets their expectations. My primary task is to enhance the current Magento system so that it supports GraphQl and also provide new API integrations required for Accor’s business needs. I am also actively engaged in the project by offering assistance to the team; I provide explanations of the requirements at each step, support FrontEnd developers and project managers in mastering the API, and oversee continuous integration of developments.

I contributed to the implementation of a marketplace (Mirakl Marketplace) at Maisons du Monde. By implementing a decoupled architecture using Magento and a VueJs FrontEnd. During this transition from a Monolithic E-Commerce solution to a Headless solution, I was responsible for designing and developing the GraphQL API as part of the Back-end development team. I collaborated closely with the business teams, architects, Front-end developers, and QA teams. The use of technologies such as Docker and Kubernetes helped us adopt a "You Build It, You Run It" approach on the Google GCP cloud.

Within the Kaliop Commerce agency, I specialized in the creation of e-commerce stores. My expertise involved aligning projects with functional project managers and developing integration and development backlogs for projects while capitalizing on the Magento / Adobe Commerce solution.

As a consultant at Cultura, I was entrusted with the maintenance of the e-commerce platform based on Magento 1 and the developement of new features. My job involved continuously optimizing the features of the online store, also thinking and creating new types of products such as digital products in the form of audio and ebooks, and providing technical support to the marketing and business departments.

At ProxymIT, I completed my end-of-study internship and was subsequently hired. In the Web Development department, I had the opportunity to explore and participate in several projects of different nature and different management methodologies. I contributed to the development of several web solutions using the LAMP stack (Magento, Prestashop, Drupal, etc.) and Java Spring Boot, from Back-end to Front-end. I also took part in the development of hybrid mobile applications.
