End-to-end AI & SaaS architect. I get AI into production: RAG systems, predictive ML and agents on cloud architectures that scale.
About Me
Software architect with 25+ years designing complex systems, now focused on getting AI into production: RAG and LLM systems, predictive ML, conversational agents and agentic automation on cloud-native architectures that scale. I've built end-to-end AI SaaS platforms —from architecture to deployment— from AIExtrusion (AI and predictive ML for industry, in production) to MyFixio (platform for repair shops and technical services, in open beta). Previously, technical lead of an AI-powered cybersecurity platform, with past work for clients like Línea Directa and Mutua Madrileña. I turn complex technical problems —and technical debt— into systems that work, stay maintainable and deliver real value.
