Fascinated by mechanics since childhood, I naturally pursued Mechanical Engineering and joined Unilever’s Unox factory, eventually leading operational roles and part of the management for major reorganizations. My experience expanded to Unilever’s headquarters, followed by a transition to consulting, where I embraced diverse challenges and navigated between operational and executive spheres effectively.
