Isabella is my AI. She knows my work, speaks your language and answers in real time — by text or by voice, on viajatech.com. Go ahead: ask her anything about me.
Now I am become Life, the creator of worlds. Walkable 3D worlds in your browser — phone, laptop, tablet, nothing to install. Two are open and a robotaxi crosses the portal between them: viajatech.com/mundos.
I also write books. Published on Amazon Kindle in English and Spanish — cybersecurity, agentic AI, health and math — written, designed and shipped end to end: my author page on Amazon · viajatech.xyz/ebooks.
I run swarms of autonomous agents. Ten specialized subagents in red and blue teams reviewed three production sites in one night; three AI designers competed through forty cover candidates; every book goes through three editorial rounds of specialized agents. Orchestrated across Claude Code, Hermes Agent, Codex and Gemini, with closed scopes, spending caps and safety hooks tested before trust: viajatech.com/perfil.
I ship AI that already works in production. I'm David Ruiz, a Creative Technologist in Mexico City. I implement text and voice assistants, autonomous agents, swarms of specialized subagents and multi-agent systems; I train models on my own datasets; I lead data-driven digital marketing; and I build websites and online stores that run with real security. Everything below is live — the proof is one click away.

| Craft | What it means |
|---|---|
| AI implementation | Text and voice assistants in production, autonomous agents and automations wired to real tools, data and processes. Isabella is the living example: real-time voice (Gemini Live) and text, a locked persona, multi-provider fallback and anti-abuse built in — on viajatech.com. |
| Agent swarms | Squads of specialized subagents that work in parallel with roles, rules, caps and independent auditors: a ten-agent red-and-blue-team security review of three production sites in one night, cover-design contests between AI designers, three-round editorial swarms for every book. The chronicle is my book Agent Squad. |
| AI training | Proprietary datasets for image, video, text and voice generation models. |
| Digital marketing & growth | Campaign segmentation, A/B testing and data interpretation to improve CPC, performance and leads. Ten years of it. |
| Campaign production | International talent — actors, actresses and celebrities — in Spanish and English; scripts, music, video editing, pre- and post-production. |
| Websites, stores & e-commerce | Sites that sell, with applied security, from $1,500 MXN, up to full online stores. Try the live demo of a business site with its own booking engine: viajatech.com/huellitas. |
| Worlds | Walkable 3D worlds that run in the browser — phone, laptop, tablet — no install, no account. Mundo 001, the city under the ceiling, and Mundo 002, the Huellitas sidewalk: a sunny street in Polanco where you walk into the model home's dog grooming salon and book an appointment without leaving the world. The robotaxi crosses the portal between them: viajatech.com/mundos. |
| Teaching & security | Tutorials and talks on AI, cybersecurity and digital marketing — Kali Linux, hashcat, recon, OSINT, digital exposure analysis with Shodan, always on my own assets. |

David Ruiz divides his time between Mexico City and whatever he has decided to understand that season. Every one of his books began as a private obsession. He publishes them when they stop being one.

Mundos: mundos caminables en 3D dentro del navegador, desde el celular, la laptop o la tablet, sin instalar nada. Hay dos abiertos, Mundo 001 «La ciudad bajo el techo» y Mundo 002 «La banqueta de Huellitas», unidos por el robotaxi: viajatech.com/mundos.
Enjambres de agentes autónomos: diseño y dirijo escuadrones de subagentes de IA especializados con roles, reglas, topes y auditores independientes. Diez subagentes en equipos rojo y azul revisaron tres sitios en producción en una noche; tres agentes diseñadores compitieron por una portada con cuarenta propuestas; cada libro pasa por tres rondas editoriales de agentes. La crónica es mi libro «Escuadrón de agentes»; el detalle, en viajatech.com/perfil.
