AI Engineer | Product Builder | LLM & Automation (Fractional CTO)
Burgos, Spain - 5:26 pm local time
While many AI solutions stay at the demo stage, I focus on turning LLM capabilities into reliable, scalable, and usable products. From document processing pipelines to AI agents and real-world automations, I design systems that integrate seamlessly into business workflows.
My background as a Fractional CTO allows me to go beyond implementation: I understand the product, the constraints, and what “working” really means for a business.
What I build
• AI agents and multi-agent systems (task orchestration, workflows)
• LLM integrations with real actions (tool / function calling)
• RAG systems (vector databases, semantic search, retrieval pipelines)
• Document processing (OCR + structured data extraction)
• End-to-end automation pipelines (LLMs + APIs + business logic)
• Internal tools powered by AI to improve operations
The goal is simple: move from “AI ideas” to systems that create real impact.
How I work
• Focus on production-ready solutions (not prototypes)
• Clean, modular, and scalable architectures
• Reliable outputs (evaluation, testing, iteration)
• Fast iteration with clear scope and deliverables
I combine speed with structure, building fast without breaking long-term scalability.
Tech Stack
Python · TypeScript · Node.js · Next.js · NestJS
OpenAI / LLM APIs · Vector Databases
PostgreSQL · MongoDB
Docker · Cloud (AWS / GCP / Hetzner / Vercel / Render)
Good fit if you need
• Turn an AI concept into a real working product
• Automate manual workflows using LLMs
• Process documents and extract structured data
• Build internal AI tools for your team
• Improve an existing AI system that is not reliable yet
