I'm Dikshit Kashyap Das — a product designer at BlackBuck working on payments infrastructure for India's commercial fleet ecosystem.
At BlackBuck, I've designed UPI products, led NPCI regulatory approvals, and built compliance flows that work for fleet operators managing 100+ trucks. Previously, I was a Senior UX Designer at Calypsu — The Product Studio.
I write about design psychology on Medium when something interesting enough comes along. I believe the best fintech design is invisible — users shouldn't have to understand the system to trust it.
