About Jessone

IT Project Manager with over 25 years of experience, I recently led complex and strategic projects at Covéa, including mainframe and distributed scheduler migrations with budgets up to 3 million euros.
In collaboration with internal and external teams, I ensured planning, steering committee facilitation, acceptance testing management, and go-lives, with a constant focus on critical service continuity.
My expertise in project management, planning, and scheduling has allowed me to oversee multi-year IT transformation programs.
I am motivated by the challenge of optimizing processes, uniting teams around common goals, and ensuring results in demanding environments.
I am seeking opportunities to continue contributing to large-scale projects in the IT infrastructure and services domain.
