― My background
Hi, I’m Heonir Feliz, a passionate Computer Science and Mathematics double major at the University of Massachusetts Amherst. With a love for problem-solving and innovation, I aim to pursue a Master’s degree immediately after graduation to deepen my expertise and contribute to impactful projects in the tech world.
Originally from the Dominican Republic, I moved to the United States alone after high school to chase my dreams and challenge myself. This journey has shaped me into a resilient, self-driven individual with a strong appreciation for growth, education, and community.
I’ve immersed myself in diverse experiences, from teaching and mentoring to exploring data science and machine learning. Outside of work and academics, you can find me learning about nutrition and bodybuilding, following soccer, or diving into foreign cinema or music. My story is one of perseverance, curiosity, and the belief that hard work can turn dreams into reality.
