About Jean-Michel

With 10 years of experience in Java development as well as all the technologies surrounding the Web, I have held the positions of Lead Developer and Operational Project Manager in a software services company, working in various fields (Agriculture, Mutual Insurance, Telecom). I then cut my teeth by becoming a Software Architect in project auditing and monitoring for a small structure. My capabilities are varied: setting up a development environment, continuous integration, testing, production, conducting functional analysis of needs, proposing adapted solutions, writing technical specifications, planning implementations, managing development teams, installations, maintenance, ticket tracking, reporting and customer follow-up. And I have also supervised interns and conducted job interviews.
