About me

I started my career back when I was a sophomore in college. My goal at the time was to build cool stuff and I was lucky enough to find people near me who wanted to do the same. Fast-forward to today and I'm still chasing after the coolest of ideas. I've worked across various domains viz. AR/VR, Productivity, Fin-tech and HR Tech.

Most recently I've been the Co-founder of Numans, an HR operations management tool for the next generation of knowledge workers.

When I'm not in front a screen, I'm usually out playing with my dogs, learning some obscure facts, trying to figure out how to reduce my carbon footprint or simply listening to podcasts.
