How Gamini is building a better working world

"Working with both public and entrepreneurial companies has helped me identify common challenges businesses face early in their journey. By sharing EY’s collective knowledge, we guide founders and executives through key growth milestones—from scaling operations to navigating acquisitions and public listings.

I believe high-performing teams thrive on engagement and diversity of thought. Mentoring is a personal passion, and I actively support individuals both within EY and externally to reach their full potential. I’m a strong advocate for diversity and inclusion, and firmly believe that inclusive environments foster stronger, more innovative teams."
