# Paulo H. Alkmin

> AI systems architect and technical leader with 25+ years building production infrastructure. I design and ship RAG pipelines, automation workflows, and LLM integrations that survive real users — not just demos. Based in São Paulo, Brazil; working worldwide. Bilingual (English / Brazilian Portuguese).

Most AI projects look impressive in demos and collapse in production. My work sits where WordPress/WooCommerce platform expertise, production AI systems (RAG, LLM integration, n8n automation), and infrastructure experience meet — the point where systems actually need to keep working six months later when nobody is watching.
