# Yuvraj Dar

> Yuvraj Dar's personal portfolio.

hey, i'm yuvraj. a student in the bay area working on artificial intelligence, computer vision, and robotics. most of it ends up as software, real apps and projects, and i care just as much about the product and entrepreneurship side: deciding what's actually worth building.

the work i care about most is the stuff that actually ships and gets used. at verdus labs i help build openhectare, an ai tool that gives farmers straight, cited answers instead of guesses, and with frc 9114 i build competition robots that have to hold up on the field.

i'm also an eagle scout, which took years of following through on something bigger than myself. that's how i try to approach everything i make.
