Back to original languageAbout Sylvain
Fullstack Java / Javascript Developer with Spring (Boot, Data, MVC, Test, Cloud) and React frameworks.
I have primarily worked as a contractor for large companies (SOCIETE GENERALE, ACCOR, DIOR, DARTY, CANAL +) to develop and maintain WEB applications (websites or intranets).
I also participated in the construction of a complete Web application in React for the software publisher Talend.
I am very interested in writing quality code, particularly through TDD, BDD, DDD methods, and testing frameworks like Mockito, Junit for the backend and Jest / MSW for the frontend.
I am also aware of good continuous integration / deployment practices, particularly through Azure Cloud technologies (Azure Devops, Kubernetes AKS, Terraform).
I can also help junior profiles to improve their skills.
