    • Hult Prize Financial Manager-Hult Prize Club USIU
      • Jan 2021 - Apr 2022

      I was honored to be part of a vibrant group of people who together pioneered the establishment of Hult Prize Club USIU as a Financial Manager. Hult Prize is a Foundation that challenges young people to solve the world’s most pressing issues through social entrepreneurship. Every year, one team receives $1M USD in funding to make their idea a reality. Responsibilities included- Drafting and implementing budgets for club activities. Raising funds by approaching prospective sponsors whose values aligned with Hult Prize. Coordinating teams of students to be cohesive in their presentations. Organizing Competitions at the different levels as they were procedural and CSR activities(visiting institutions for the needy). The role was very dynamic and rewarding as it broadened my mindset to think outside the box and sharpened my social, team-leading, event-organizing marketing and money management skills. Show less
