Data & AI Engineer | Pipelines, BI & AI Assistants on Your Data

I build AI assistants and data systems that run on your real business data — not demos. From clean pipelines to dashboards to LLM agents that answer questions and trigger actions, I connect all three so they hold together in production. Most AI projects break because they're bolted onto messy data. With 15+ years across the full data lifecycle, I build the foundation and the intelligent layer on top — so the result actually works. What I do: • AI assistants & agents on your data — chat in plain English, or automate tasks end-to-end (LLM integration, n8n, RAG) • Data pipelines — dbt on Postgres, SQL Server, BigQuery, with automated quality checks • BI & dashboards — Power BI and Looker Studio, 10+ years, built for non-technical teams • AI in existing processes — document reading, classification, extraction I work with frontier models (OpenAI, Anthropic) or private/local models when your data can't leave your systems — your call. Based in Argentina, fully aligned with US business hours — real-time collaboration, not overnight handoffs. If your data is stuck, your reporting is a mess, or your AI works in a demo but not on real data — send me a message and let's talk.
