About Me

Get to know me!

I'm a senior Computer Science student graduating in December 2025, and I've just finished my exchange semester at UC Berkeley. During my time at Berkeley, I got to build several MVPs and pitch to VCs, where I learned a lot about solving the right problems and building fast. I'm currently working as a Software Engineer intern on mobile for Banter, an AI Messenger startup. I love building things that make people's lives easier and I'm passionate about creating innovative solutions and exploring new technologies.



When I'm not coding, you can find me playing table tennis, getting lost in interesting podcasts, or reading about new tech. Always up for learning new things and meeting fellow developers!
