Your engineers shouldn't waste hours searching through manuals
22 years in industrial operations. I turn technical docs into AI assistants.

Built by an engineer who understands your workflows and challenges
About me
Hi! I'm Juanjo, a Freelance AI Engineer based in Madrid, Spain. I work with energy and engineering companies struggling to access critical knowledge buried in technical documentation. Whether you have procedures scattered across 500-page PDFs or institutional knowledge trapped in the heads of senior employees—the challenge is the same: your teams waste hours searching instead of doing.
I bring a unique combination: 22 years as a Drilling Engineer in oil & gas (Repsol, ADNOC, Moeve) plus hands-on AI development experience. I hold a PhD in Engineering and I'm a certified Python developer. I've built RAG systems, AI classification agents, and workflow automation tools that solve real operational problems.
My tech stack includes Python, FastAPI, LangChain, PostgreSQL, Weaviate, Pinecone, OpenAI, Anthropic, and automation tools like n8n and Make.
Why work with me?
Here's what sets me apart and how I can help drive value for your business:
-
I Speak Your Language
With 22 years in drilling and industrial operations, I understand your workflows, safety requirements, and engineering challenges. You won't waste time explaining your business to me—I've lived it.
-
Engineer + AI Developer
PhD in Engineering plus certified Python developer. I combine deep technical expertise with practical AI implementation skills. My solutions are built on real-world experience, not just theory.
-
Documentation Expert
I specialize in turning complex technical documentation into intelligent, searchable knowledge bases. Your teams get instant answers instead of hours digging through manuals.
-
Practical AI, Not Hype
I focus on solutions that deliver measurable results: reduced search time, fewer errors, faster onboarding. No buzzwords, no over-engineering—just AI that works for your operations.
What my past clients say about my work
Frequently asked questions
How quickly can you start working on my project?
I can typically begin new projects within 1-2 weeks of our discovery call. For urgent matters, I maintain some flexibility and can potentially start sooner—just let me know your timeline during our initial consultation.
Do you require a minimum project size or commitment?
While I can accommodate projects of various sizes, I find that engagements of at least 40 hours allow for meaningful impact. This gives us enough time to understand your documentation, build a proper RAG system, and deliver a solution your teams will actually use. We can start with a small pilot project to ensure we're a good fit.
What industries do you have experience in?
I specialize in energy, oil & gas, and industrial engineering—industries where I've worked for 22 years. I understand the technical language, safety requirements, and operational workflows. That said, my AI solutions apply to any organization with complex technical documentation: manufacturing, utilities, construction, or any engineering-heavy sector.
How do you handle data security and confidentiality?
I take data security extremely seriously—I've worked with sensitive operational data my entire career. I sign comprehensive NDAs before starting any project, use enterprise-grade encryption for all data transfers, and can work entirely within your existing security infrastructure. Your technical documentation stays protected.
What's your pricing structure?
I offer both project-based and retainer pricing models. Project fees are based on scope, complexity, and value delivered rather than just hours worked. For ongoing support and system optimization, I offer flexible retainer packages. Let's discuss your specific needs during our free strategy call to determine the best approach.
How do you communicate progress and results?
I maintain clear communication through weekly progress updates and regular check-in meetings. You'll receive full documentation of the system architecture, implementation details, and user guides. I also provide training for your team so they can get the most out of the AI assistant we build together.
