01 — About

Technology should break down barriers, not build new ones.

I'm the co-founder of Decaf, a fintech platform making global financial services accessible to everyone. We operate in 180+ countries, enabling cross-border payments with lower fees through a non-custodial wallet — giving people control over their finances, especially those excluded from traditional banking.

Outside of Decaf, I serve as Curator of the Global Shapers Mexico City Hub, working with young leaders on projects that tackle local and global challenges. I've seen firsthand that technology and community together create outsized change.

Before founding Decaf, I spent years building marketing automation systems that managed tens of millions of dollars in spend, and shipped award-winning accessibility and blockchain projects along the way.

Decaf

Co-Founder · 2022 — now

In much of the world, getting paid is the hard part: Stripe isn't available, and cross-border fees can swallow up to 20% of a payment.

Decaf gives anyone a payment link in minutes. Clients pay by card, bank transfer, or crypto — and users keep 99%. Under the hood, a non-custodial wallet bridges fiat and crypto rails.

As co-founder, I build the product end to end — payment infrastructure, wallet UX, and the rails between them.
