Bio

I was the founding engineer of leading startups like MediaIQ and Hevodata and was among the initial 10 employees of both these companies. I have also spent considerable time in large companies like Flipkart and Applied Materials. Besides that, I am a huge movie buff and like watching and playing cricket.
