RSS FeedI'm a product leader who builds. I've spent nearly 15 years taking digital products from strategy to launch in fintech and telecom, and I write the code myself.
Hands-on engineering
I co-founded Foambyte®, a production-management platform for craft brewers, with my brother Diego, a brewmaster with 12+ years of experience who leads the product as CPO. I'm the CEO and the only developer: I designed and built the entire platform (architecture, frontend, backend, mobile and infrastructure) using React, TypeScript, Hono, TanStack, Tailwind, CapacitorJS, and edge infrastructure on Cloudflare and PlanetScale Postgres. Together we've grown it to 100+ users in 3 countries.
Product & business leadership
At Fiserv I led product strategy for Digital Solutions (online & mobile banking, card management, mobile wallet, payments) across Latin America and the Caribbean. I launched the DigitalAccess omni-channel platform, push provisioning, and a developer portal for banking APIs, and my team delivered double-digit revenue growth and beat quota six years in a row. At Nextel México (now AT&T México) I led a 15+ person team and launched 3G voice & data services and top-up channels with BBVA, HSBC and Walmart, worth tens of millions of USD a year.
