About Facundo

I am an AI Engineer and Co-Founder. I specialize in designing systems where AI is not a decorative layer, but a core product capability.

I build automation architectures to solve complex operational problems in healthcare, government, and SaaS. I have developed everything from microservices with intelligent scraping of public portals to clinical audit solutions with LLMs and AI-native platforms conceived from the ground up.

I currently lead AI engineering in the Colombian healthcare sector (Grupo Campbell) and, in parallel, am building Sazonia as Co-Founder — a modular AI-native SaaS platform for restaurants that bridges the gap between expensive and complex enterprise POS systems and cheap but limited QR menu apps.

My main stack: TypeScript · Node.js · Next.js · event-driven architectures.

🧠 My differential approach

— Design AI layers with control, traceability, and clear boundaries
— Apply Context Engineering for consistent and reproducible results
— Automate complex workflows with n8n, integrating multiple platforms
— I think of every solution for production, not for demos
— AI governance from day 0: confidence thresholds, prompt versioning, human review in the grey zone

🚀 How can I help you?

✨ Custom Automations — workflows that reduce errors and save real operational time
⚙️ AI layers for product — integration of LLMs as a core capability, not a decorative feature
📦 SaaS Agent-Ready — products designed to work with agents from the first sprint

I believe in useful, traceable, and governable AI. If it doesn't generate real, measurable impact, it's not well integrated.
