    About me

    I'm a founding product engineer at Flexrad, working remote from India. I like owning things end to end, from the API to the last pixel.

    Before code, I won a national inline hockey title with Team Andhra (2014 to 2017), and I placed fourth in the world in NASA's Space Settlement Contest in 2017.
