Back to original languageAbout Jose Carlos
I help SMEs, startups, and professional firms put artificial intelligence to real work: chatbots that don't invent data, automations that save hours every week, and modern web applications with integrated AI.
Do you have an AI assistant that works in the demo but hallucinates, is too expensive, or can't handle production? That's where I come in.
What I can do for you:
· AI Chatbots and Assistants (Claude, GPT, Gemini) connected to your data, with anti-hallucination verification and controlled token costs.
· Production RAG Systems: retrieval with source verification and citation validation. Ideal for regulated sectors (legal, health, finance).
· Process Automation with n8n and Make: invoicing, CRM, email, reporting, scraping. Special experience with consultancies and law firms.
· Custom Web Development (Next.js/React + Python/FastAPI) with integrated AI, Stripe payments, and Google Cloud deployment.
· LLM Agents for multi-step tasks and agentic workflows.
My proof: I am CTO of Dictalegal, a legal AI SaaS for Spanish law where every legal citation is validated before being shown: it's checked that the reference exists and is real. In a domain where inventing a ruling is unacceptable, that's the difference between a toy and a work tool.
How I work: architecture first, each phase closed and verified before opening the next, and "done" means deployed and working. Direct communication, realistic deadlines, and response within 24 hours.
Do you have a repetitive process to automate or an AI pilot that needs to go into production? Let's talk.
