After more than10 years of experiencein business development, team management, and corporate strategy, I chose to put my expertise to the service oftraining and knowledge transfer.

Throughout my career, I have supported teams in their skill development, driven ambitious growth strategies, and led impactful decision-making. My background, combiningoperational management, mentoring, and business unit development**, has allowed me to understand **the real challenges of the professional worldand transform them into concrete and applicable lessons.

Today, I work as atrainer and speakeron topics such as:

- **Project Methodology**: from resource management to performance optimization.

- **Business Management**: leadership, team management, and growth strategies.

- **Commercial Development and Customer Relations**: structuring offers and customer loyalty.
