Back to original languageAbout Jayson
Passionate about development for several years, I simply enjoy designing and evolving useful, clean, and user-friendly web applications. My daily work mainly revolves around Java (Spring Boot) for the backend and React for the frontend. Through my experiences, particularly in adding new business features to an existing HRIS and developing an e-commerce platform, I've also learned about DevOps with Docker and CI/CD to deliver robust projects. What I bring to a project: Team spirit & listening: I enjoy discussing, understanding users' real needs, and working in a good atmosphere. Adaptability & rigor: Capable of quickly diving into an existing project, producing clean code, testing what I develop (TDD), and continuing to learn. Versatility: From React components to deployment, I can lend a hand across the entire chain. Based between Lille and Nantes, I am available to discuss your projects, whether locally or remotely. Looking forward to chatting!
