About

Hi there! I'm Harsh, a: Hacker. Tinkerer. Changemaker. I'm an entrepreneur at heart but I enjoy diving into the world of computer science and solving complex problems. My passions lay in backend and infrastructure development, cybersecurity, quantitative trading, and applied AI. I recently graduated from UC Davis with a bachelor’s degree in computer science with an emphasis in operating systems, AI, and networks. I be continuing my studies at UIUC and working towards a Masters in Computer Science with a concentration in AI/ML infrastructure and am a part of several campus initiatives where I am working on the intersection of my passions. Outside of my academic and professional life, I have also recently discovered newfound passions for basketball, game theory, and chess. I am always willing to explore new opportunities and have a quick chat!
