Santiago Villavicencio

Software engineer & fintech builder in Mexico City

I build payment infrastructure. I co-founded Klu Carpay, where we tokenize vehicle license plates as a payment method: cameras recognize your plate and the transaction just happens. Today I'm a product engineer at Bitrus Exchange, leading a team of developers and translating between business and engineering. Before that I shipped full-stack products across mining analytics, consulting, and e-commerce.
