About

With nearly four years of leadership experience, I recently completed my MBA in Leadership, Team Management, and Productivity at PUC-RS, further enhancing my skills in management and people development. I believe that effective leadership goes beyond managing processes—it’s about inspiring, empowering, and creating an environment where people can reach their full potential. My work is focused on strategic management and talent development, ensuring efficient support and high-impact solutions. I hold a degree in Business Administration and have expertise in International Business and Foreign Trade from Centro Universitário Senac, which provides me with a broad, results-oriented perspective. Additionally, I had the opportunity to gain international experience in Australia, where I deepened my knowledge in communication, diversity, and cultural dynamics. This experience broadened my perspective on global collaboration and the importance of an inclusive environment for both personal and professional growth. I am driven by a commitment to excellence, innovation, and continuous growth. My goal is to create a positive impact on people and organizations through human-centered leadership focused on results.
