The first video I watched of Armaan was on Raju's YouTube channel. At first, I didn’t expect Armaan to be so good at teaching bug bounty . Initially, I doubted whether he could actually find bugs, but once he started, he didn’t stop—and he truly impressed me. Since then, I’ve been following Armaan regularly, and my confidence in bug bounty has grown significantly. I’ve even found a few bugs in my college systems. All credit goes to Armaan for inspiring and guiding me.
