About
I’m Juan Cruz, a full-stack developer with a university degree in Programming (UTN FRM, Mendoza). Since 2024 I’ve been building software for clients who use it every day: catalogs, ordering platforms with payments, and process automation.
My strongest evidence is on the frontend (React, Next.js, strict TypeScript), but I deliver the whole system: FastAPI backends, PostgreSQL schemas, role-based access control, payments and real-time updates. What I pay most attention to is the seams between layers, which is where the hard failures live.
Before that I worked at RST Argentina, building interfaces for digital health platforms. My final project was a post-sale automation system on n8n, formally audited.
I hold Italian citizenship, so I can work anywhere in the EU without sponsorship. I work in English at C1, speak basic German, and I’m looking for a remote role on an international team or a position in Europe.
