About

My CS journey all started with a Python tutorial on YouTube. It was immediately clear after the first few hours of watching that once I learned how to program, I could build anything. The pursuit of that kind of freedom has carried me through my undergrad years at CMU and into the work I do today. Never did I anticipate back then how the power of AI would amplify that momentum.

I believe that technology, when guided by an innovative mind, can make a positive impact on this world. To this end, I want to write the code that makes things happen :-)— Hao
