Randstad France, a major player in Human Resources services, has over 10,000 employees, 830 agencies in the country, and generated revenue of 3.6 billion euros in 2024.

I worked on a B2B web application for 3,500 healthcare facilities, managing staff replacements. The platform automates the connection between facilities and temporary workers (TW) to replace absent employees (sick leave, vacation, etc.). It handles approximately 15,000 replacement requests per month, while the mobile application, used daily by nearly 10,000 temporary workers, allows them to manage these proposed assignments.

I acted as Tech Lead for a team of 4 people, responsible for the API and front-end of the Appel Médical tool.

I collaborated with the team in charge of the Randstad business backend API. All within a NoEstimate approach, focused on flow and continuous delivery.

- Adoption of a modular monolith based on DDD

- Transition to an event-driven architecture

Missions on the front-end redesign

- Progressive deployment with the old front-end

- Migration from JavaScript to TypeScript, and from Vue.js to React

I also contributed to mentoring and upskilling the team.

I provided training on topics such as TDD, DDD, CQRS, Clean Architecture, etc.
