Sobre mim
Full stack developer building real, production-grade apps. I run two of my own products in production - booklo (book marketplace, 30,000+ titles, live Mercado Pago payments) and investy (financial data and investment scoring engine) - real users, not demos.
Documentation-first: every project starts with a written spec. Full stack across React, Next js, Angular, Node js, Java Spring Boot, PostgreSQL and MySQL. Native Spanish, advanced English. Based in Argentina, available remote with flexible hours.

Jan 2026 - Present • 7 mos
I design, build and run my own products end to end: booklo.com.ar, a book marketplace with a 30,000+ title catalog, Mercado Pago checkout, Google OAuth and an admin dashboard (Angular, TypeScript, Node.js, Express, MySQL); and investy.com.ar, a market data platform that scores 36+ Argentine instruments with a 5-factor quantitative model (TypeScript, NestJS, MySQL, Python). I handle everything from database schema to deployment on my own Linux server with nginx, HTTPS and Cloudflare.
