At Fundación Integra España, I designed and shipped RAG architectures to automate business processes, including travel-expense processing that cut administrative time by 80%. I also worked with operational teams on requirements, architecture, and process redesign.

As a freelance Full-Stack Developer, I built digital products and AI-powered applications for real client use cases, taking projects from requirements through deployment. My work has included a chatbot using ChromaDB and Anthropic API, and Python OCR workflows for ERP integration.

Before focusing on AI and software, I worked across operations, process transformation, and data analysis at ALLCOT Group, ALLCOT Trading, Anheuser-Busch InBev, and Di Bacco y Cía S.A. I bring that process experience into solution design, connecting business needs with working technical systems.
