About Marie

Freelance administrative and operational assistant based in Brussels, I support organizations in their daily management: file tracking, coordination, executive assistance, and internal organization.

With several years of experience in associative and institutional environments, I have developed solid skills in agenda management, meeting organization, minute-taking, document preparation, and rigorous administrative follow-up.

I also led an entrepreneurial project supported by JobYourself, which strengthened my autonomy, organizational skills, and service-oriented approach.

Available for one-off or regular missions, remotely or on-site in Brussels, I integrate quickly to provide reliable, structured, and efficient support to teams and managers.
