About Nestor
AI Builder, Automations, AI Agents & Full-Stack Web Apps
Boadilla del Monte, Spain - 1:56 am local time
What I can do for you:
• Workflow automation with n8n (CRMs, invoicing, lead capture, notifications)
• AI voice agents & chatbots (Retell AI, OpenAI, WhatsApp) that qualify leads and book calls
• Custom web apps & SaaS dashboards (Next.js, React, Supabase, PostgreSQL)
• Membership platforms, community walls, and role-based content systems
• Automated document generation (PDF proposals, quotes, reports)
My stack: n8n · OpenAI & Claude APIs · Retell AI · Next.js · React · TypeScript · Supabase · PostgreSQL · WhatsApp API · Vercel.
Recently certified by the people building this technology:
• Google AI Professional Certificate (7 courses)
• Claude Code: Software Engineering with Generative AI Agents — Vanderbilt University
• AI Fundamentals with Claude — Anthropic
I come from a no-code/automation background (n8n, Make), so I think in terms of business outcomes first and code second — I don't over-engineer; I ship what moves the needle.
Bonus: I'm a native Spanish speaker and work comfortably with English-speaking clients, so I'm a great fit if you need someone bridging both markets.
Let's talk about what you're trying to automate or build — send me a message and I'll tell you honestly whether I'm the right fit.
