About Kévin

Finding the best, most economical solution, building the team, and finally delivering the project, that's where my pleasure lies!

I've had the opportunity to work on numerous projects with varied contexts and technologies, which has allowed me to strengthen my skills in software architecture and information systems.

I've also had several occasions to be a Project Manager, manager, tech lead, providing a clear vision of project objectives, and always demonstrating the way forward has been a comfort to the teams I've supervised.

Also often confronted with business needs, in gathering requirements, for acceptance testing, communication, synthesis skills, modeling, and representation techniques are all key elements.

At all levels and to reinforce the discourse and support decision-making, I implement the appropriate KPIs, whether for tracking UX or prioritizing tasks.

Around Java, Javascript, Angular, React, Flutter technologies, but much more than that, you can entrust your projects to me with confidence; strategic consulting, design, monitoring, delivery, I can intervene at all stages of a project.

So don't hesitate, call on me, I am currently free of commitments!
