Greeting
Hey there! Thanks for visiting my personal website.
I am pursuing my Master's degree in Data Science at the NYU Center for Data Science. Additionally, I worked as a data science intern at Meta during the summer of 2025 in the Menlo Park HQ office.
Looking forward to connecting with you!
Everyday, 400 million terabytes of data are created.
As an aspiring Data Scientist, I find it exciting to unlock the power of data, whether it is through AI technologies or useful insights. If I am good enough to use data to directly benefit the society, it would be even more rewarding.
Excited for the path that lies ahead.
