    I recently participated in a hackathon at Yale University, where my team and I won 1st place in the Education Track! We developed a program called SlideForge, an innovative solution designed to enhance educational experiences. Collaborating with talented developers, I had the chance to push my limits, learn new skills, and create an impactful project that addressed real-world challenges. I am incredibly proud of what we accomplished, and I'm excited to continue building on this momentum.

    Codedex Hackathon

    Remote

    This was my first hackathon experience, where I had the opportunity to collaborate with two talented peers who were equally new to the environment. We gained invaluable insights into collaborative coding and teamwork. My primary responsibilities included developing the Three.js model and the Event page. The hackathon was an excellent learning opportunity, and I am eager to participate in more hackathons in the future to continue working with other innovative and skilled individuals.
