Juan Cortez is a technology leader and hands-on software engineer with 10 years of experience building AI-driven products and production ML infrastructure across startups in Chile. Currently a Team Manager at Fintual, he scaled a hybrid support team into a fully staffed engineering unit and is leading efforts to bring customer support ownership in-house to surface product improvement opportunities. Previously he shipped an autonomous customer support AI handling ~6,000 conversations/month with 80% CSAT and built a 1,000+ QA evaluation dataset to iteratively improve agent performance. At NotCo he combined people leadership and IC work as Lead ML Engineer, owning OKRs, CI/CD for models, and cross-functional product development informed by user research. He blends deep technical chops (UMAP, HDBSCAN, model/data versioning, ML ops) with product-minded execution and a continual learning mindset honed at Universidad de Chile and an exchange at UC Irvine.
