Profile & contact

For employers, brands and businesses. I ship text and voice AI, train models, lead data-driven digital marketing and build websites and online stores.

Time in Mexico City

I'm David.

Creative Technologist. I implement artificial intelligence that already runs in production: text and voice assistants, autonomous agents and multi-agent systems that connect tools, data, and processes to turn complex ideas into usable product. I train image, video, text and voice generation models on proprietary datasets. I build websites, digital stores and e-commerce where identity, content, and business share architecture — this site is one of them.

I operate between terminal and browser. OSINT, cybersecurity research, digital exposure analysis with Shodan, automation at scale. I publish part of the process in tutorials — Kali Linux, hashcat, recon, offensive security in controlled environments — because technical knowledge shouldn't feel hostile. github.com/viajatech holds part of the work.

I conceptualize and execute end-to-end digital campaigns: strategy, scripts in Spanish and English, recruiting and directing international talent — actors, actresses and celebrities —, music, video editing, pre- and post-production, social media marketing. I segment, run A/B tests and read the data to lower CPC and raise performance and leads. My models and agents orchestrate publishing, generate imagery and maintain presence across platforms. E-commerce and online sales close the loop — build brand, move attention, convert.

I'm demanding, competitive and accountable: what I promise, I deliver. Technology, creativity, data and business: the same material edited into different cuts.

Solutions that don't just work — they feel.

What I do

AI implementation: text and voice assistants in production, autonomous agents and automations wired to real tools, data and processes.
Autonomous agent swarms: I design and direct squads of specialized AI subagents that work in parallel with roles, rules, caps and independent auditors; from cybersecurity to design and editing.
AI training: proprietary datasets for image, video, text and voice generation models.
Digital marketing and growth: campaign segmentation, A/B testing and data interpretation to improve CPC, performance and leads.
Campaign production: recruiting international talent (actors, actresses and celebrities) in Spanish and English; scripts, music, video editing, pre- and post-production.
Websites, digital stores and e-commerce in production, with applied security: this site, jettrendy.com and viajatech.xyz are mine.
Virtual worlds: walkable 3D environments in the browser, for phone, laptop and tablet, nothing to install. The first one is already open at /mundos.
Books: published author on Amazon Kindle and viajatech.xyz, in English and Spanish: cybersecurity, agentic AI, health and math.
Teaching: tutorials and talks on social media about AI, cybersecurity and digital marketing. Member of Instagram's closed creators community (@igcreatorscommunity).

Autonomous agent swarms

Swarm architect: an orchestrator splits the work, specialized subagents execute it in parallel and independent auditors check it before I approve it. Not a promise: this is how these things got done.

Cybersecurity, red team and blue team: a squad of ten subagents — analysts, scrum masters, supervisors and auditors — reviewed three production sites in one night, with the owner's permission, a local lab of planted flaws and independent verification of every finding. The full chronicle is my book, Agent Squad.
Design by contest: three AI designers competed for that book's cover across three rounds and forty candidates, with bespoke typography, a 100-pixel store simulation and a verdict based on sales. The winner is on Amazon.
Editing by swarm: every book goes through three rounds of specialized subagents — developmental editor, novelist, reader psychologist, beginner reader, technical reviewer and designer — that critique, verify against the source and propose; I decide.
Daily production: agents that code, publish to six networks, generate imagery, run the store and build 3D worlds, orchestrated across Claude Code, Hermes Agent, Codex, Gemini and local models, with closed scopes, spending caps and safety hooks that get tested before they're trusted.
