Full-stack developer who ships complete products — API, database and interface — with a centre of gravity on
the backend. On the Customer Success team at Chatty, a WhatsApp CRM platform, I take clients through
implementation and build the AI agents, automations and custom metrics they run their sales on. In parallel,
five years inside a pediatric pathology research institute — invoicing diagnostic and genomic services,
regulatory and bioethics records, and the IT behind them — after training as a radiology technician at the
University of Buenos Aires. I work in Node.js, TypeScript, PostgreSQL and
React, and model operational and clinical domains from experience rather than from a spec.
