About
Hey, I’m Himanshu, Senior PM at Paytm, owning OAuth & Device Binding for 300 M+ users. I obsess over the five-second window where trust is won or lost. Nights find me writing a public journaling lab on my portfolio (dropping soon) to ship raw, in-progress lessons. Side hustle: Product Unshipped - a Substack that tears down growth loops, AI workflows, and the gnarly Indian-fintech edge cases most folks ignore. 350+ builders tune in for essays like “AI Loops in the Wild” and “The Five-Second Rule.”
