Full-stack software engineer and founder at Focal Partners, building three SaaS products for bookings, loyalty, and payments.
ChileWhat I'm looking for
At Focal Partners, I’m building three SaaS products for bookings, loyalty, and payments. For TuBarberIA, I built a subscription SaaS and marketplace for barbershop bookings and sales with Next.js, TypeScript, tRPC, Prisma, and Supabase.
I extended the shared architecture into a management SaaS and booking marketplace for car-service businesses, reusing three shared monorepo packages to cut delivery time. At Lazoo, I led the v2 rebuild of a loyalty SaaS with Apple and Google Wallet passes and QR check-ins, shipping fixes and features to the v1 production app.
My earlier work includes maintaining a metallurgical balance platform for CMP mining operations and delivering software for logistics, ticketing, fintech, and public-sector systems. I’ve also worked with remote U.S. teams and used AI-assisted workflows, including Cursor and Claude Code.
