# Vinod Rajpurohit > Designer and builder humanizing technology. Fourteen years in commerce and payments, currently leading design for checkout, growth, and AI at PayPal, based in the San Francisco Bay Area. Vinod Rajpurohit has spent fourteen years designing how the moment of payment works, across three chapters: Chennai, Singapore, and San Francisco. Someone, somewhere, is paying for something right now, and his homepage is a quiet living portrait of that idea: a world clock of cities riding their own hours, a simulated ledger of small human purchases in local currencies, and a coin you can flick into a jar. Outside of work he builds independent products and experiments, including Bolt (an AI commerce copilot), HueKit (open-source OKLCH color tooling), Riff (an AI collaborator for FigJam ideation), and Ember (a browser game played with your breath). ## Links - [Home](https://vinod.me/) - [Work](https://def.vinod.me/): private commerce, checkout, payments, and AI case studies. - [Playground](https://ember.vinod.me/): small games and live experiments. - [GitHub](https://github.com/doniv01) - [X / Twitter](https://x.com/doniv01) - [LinkedIn](https://www.linkedin.com/in/vinod01) ## Notes - Contact: hello@vinod.me - The purchases on the homepage are simulated and labeled as such; the clocks are real. - Work case studies are private and shared on request.
