About

1st Apr Update: Shaping tomorrow's Agentic Commerce. I've been a techie all my life. Before I even learned about Dial-Up Broadband in textbooks, I was using it. My dad's office had just installed BSNL broadband and a brand-new HCL Desktop, and I was hooked. I explored the early 2000s internet, from flash games to songs.pk to torrents. Since then, technology has been a part of my life. I'm not much of a phone person - 95% of my screen time is on my laptop. From my early school days, I've been building stuff. From websites to web browsers, I love the grind of turning an idea into a product. The more absurd or difficult the idea, the bigger the dopamine hit. After four years of learning and building at Exotel, I've realised that creating something people love is my true calling. And right now, I'm going after it.
