Oct 2025 - Present • 9 mos

Technical founder of a local services marketplace in Brazil. I built the entire product: Next.js frontend, Supabase backend, Vercel deployment, plus the lead capture and booking flows that connect local service providers with clients. Beyond the code, I own the acquisition side: landing page copy, local SEO, and the automated follow up sequences that convert a form submission into a booked appointment. This is the same system I build for clients, running in production against real users and real revenue.
