========== ABOUT ME ==========
My name is Kajal Gada. I am a Robotics Software Engineer and a youtuber. My goal is to develop algorithms for realizing robot operations in the real world. And it is just absolute fun to code and solve problems.

I started my journey in Robotics by working on small personal projects such as a line follower with an arduino. I then pursued and graduated with a Masters in Robotics from University of Maryland in 2017. After graduation, I have worked at Reality AI, Qualcomm and Brain Corp.

I am also a YouTuber, it is my way of giving back and helping the community grow. As a women and an international student in the US, I am aware of the challenges to break through and have a successful career. I share my insights and also teach robotics through my youtube channel.
