Hey, I’m Harmeet.
Security Engineer

I work at Paytm and work towards securing their payment gateways and banking services. I am an active bug bounty hunter who goes by the name of Theia and loves to catch bugs spawning in applications and infrastructure available publicly on the internet. Security is love, and of course, my bread-butter.
