About

Hello! It's great to connect with you! I'm a Mechanical Engineering undergraduate at USC's Viterbi School of Engineering, where my academic pursuits meet my passion for innovation and problem-solving. Alongside my studies, I indulge in playing guitar and engaging in sports, constantly seeking new challenges and experiences. The words of Hazrat Inayat Khan resonate deeply with me: "I asked for strength and God gave me difficulties to make me strong. I asked for wisdom and God gave me problems to learn to solve. I asked for courage and God gave me dangers to overcome. I asked for love and God gave me people to help. I received nothing I wanted. I received everything I needed." Embracing these principles, I'm committed to overcoming obstacles and pursuing my goals with determination. I aim to make a meaningful difference in the lives of others through my actions and leadership. Myer-Briggs Indicator: INFJ-T Let's connect! I'm looking forward to putting our minds together.
