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 Sattotal (the operating system for repair shops, in production). 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.

The operating system for repair shops
I designed and built it end to end: repairs, quotes, POS and invoicing, inventory, warranties and AI in a single platform, with no installation and from any device. Launched in June 2026, it is already used by repair shops across Europe and the Americas.
