At Amaris Consulting, I led the technical delivery of Foodie for Cencosud, an in-app and self-service food-ordering platform processing 1K+ orders weekly. I worked across its React and React Native experiences, kiosks, KDS applications, backend services, and operational backoffice.

I delivered workflows and integrations using React, TypeScript, Node.js, and Go, and owned features from product discussions through release and production monitoring. I also contributed to an AI-powered assistant using LLMs, RAG, tool calling, and AI agents.

At Coopeuch, I delivered digital banking features across React and React Native applications serving 1M+ active members, and built Node.js/NestJS services and BFF layers. Earlier, I migrated business modules at AgendaPro and developed web and mobile features for clients at Vascar Solutions.
