For employers

AI Engineer for agentic production systems.

I build and lead AI-native creative production systems that turn creative ideas into high-impact content at scale: more speed, more variants and conversion-focused creative.

    Experience

    Global Media Review Inc. | La Neta / Elevn

    AI Research, Content Creation & Workflow Builder

    Worked across AI research, creative production and workflow development for a creator-economy environment serving major brands including Nescafé, Dove and Levi’s, focused on commercial, social and UGC content.

    Production speed & scale

    • Reduced time per piece from 3 days to 1.5 days and now to ~30 min (−99%): from manual production to automated, AI-powered workflows, enabling a high weekly volume of variants for testing.
    • Designed agentic production systems combining audiovisual knowledge, instructions, tools, validation and human oversight to scale volume without losing control.
    • Built node-based pipelines connecting generative models, control logic, transformations and quality checks.

    High-impact content & performance creative

    • Produced commercial, retail, social and UGC creative for Nescafé, Sears and Dove, with CTR- and conversion-focused creative and multiple variants for A/B testing.
    • Clients consistently satisfied with extra AI-generated pieces delivered as added value.
    • Benchmarked live video, image, audio and multimodal models for quality, consistency, control, speed and commercial viability.
    • Converted production expertise and research findings into structured agent knowledge, specifications and reusable operating logic that speeds up every creative cycle.

    Brand, quality & teams

    • Applied human-in-the-loop guardrails, correction and final craft to protect brand fidelity and creative quality at scale.
    • Documented reusable production methods so non-technical teams could operate sophisticated AI production workflows and scale content production.

    Multi-sector AI production platform

    Product, architecture and production

    I designed and built an AI production platform that serves eleven sectors from one system. The services on this site come from its catalogs.

    What it is made of

    • An agent engine in Python and a web app in React 19 + TypeScript, with a landing, a client app and an operator console.
    • Eleven bilingual (EN/ES) sector sites, each with its own service catalog: units, scope rules and guardrails.
    • The work model is part of the product: the client asks, the system proposes, and nothing is delivered until the client approves.

    Creator production & early AI

    EG_WICHO | ELGAMERWICHO

    Video editor · Social media manager · Thumbnails & SEO

    Worked for influencer and content creator @EG_WICHO on video editing, social media and YouTube creative.

    Contributions

    • Edited creator-led videos with storytelling, motion graphics, color, sound and hands-on finishing.
    • Managed social media content, designed thumbnails and supported YouTube SEO and content discovery.
    • This is where I first integrated AI into my creative process, alongside traditional editing and design.

02

Skills.

AI engineering, the creative and growth work it serves, and the hands-on craft underneath.

AI engineering

  • LLM agents

    Configuring a model with system instructions, knowledge, state and tools to do a defined class of work.

  • MCP, APIs & webhooks

    Concrete interfaces that let an agent drive workflows, services and jobs.

  • Node-based pipelines

    Graphs that connect generative models, control logic, transformations and quality checks.

  • Cloud execution

    Workflows as callable units on managed compute, with job management and concurrency.

  • Generative specification

    Turning human intent into structured, receiver-aware specifications before generation.

  • Model evaluation

    Benchmarking video, image, audio and multimodal models against real production requirements.

  • Human-in-the-loop QA

    Guardrails, correction and final craft that protect fidelity and quality at scale.

  • Product engineering

    An agent engine in Python and a web app in React 19 + TypeScript, with client and operator views.

AI-native creative growth

  • Creative production

    Static images, product visuals, advertising creatives, UGC-style content and short-form video, supported by professional editing, motion graphics, color grading and sound design.

  • Content marketing & creative strategy

    Content development, creative direction, messaging, and formats shaped around channels and specific marketing objectives.

  • Growth & conversion

    Creative aligned with acquisition objectives, campaign concepts, landing pages, funnels, and learning-informed iteration.

  • Agentic AI & creative systems

    Claude, ChatGPT, structured instructions, reusable workflows, automation, validation, and human oversight.

Hands-on craft & deliverables

  • Narrative editing

    Storytelling, pacing, footage selection and assembly.

  • Motion & VFX

    Compositing, kinetic type, animated graphics and effects.

  • Color & sound

    Color correction, grading, music and sound design.

  • Thumbnails & SEO

    Visual hooks, YouTube packaging and discoverability.

  • Social formats

    Shorts, Reels, TikTok, subtitles and aspect ratios.

  • Graphic design

    Branding, marketing graphics and infographics.

Agentic AI creative architecture.

The systems, knowledge, workflows and production infrastructure that turn intelligence into executable creative production.

Full document (PDF) →
  1. 01

    Intent

    Human defines the objective, references, constraints, and required outcome.

  2. 02

    Reasoning

    The selected LLM interprets the objective using system instructions and operational knowledge.

  3. 03

    Specification

    The agent creates the production specification required by the chosen capability.

  4. 04

    Workflow

    The agent constructs or selects the node graph required to execute the specification.

  5. 05

    Execution

    The graph is submitted to the cloud production platform through an available interface.

  6. 06

    Generation

    Specialized models inside the graph create or transform media.

  7. 07

    Validation

    The result is checked against creative and technical criteria; corrections are made where needed.

  8. 08

    Outcome

    Approved media is delivered for its intended creative or commercial use.

Architectural principles

  • Composable · each component has a defined responsibility and explicit interface.
  • Capability-driven · models and workflows are selected according to production requirements.
  • Knowledge-first · complex execution depends on domain and operational knowledge, not only model capability.
  • Specification-driven · intent is converted into structured, receiver-aware execution instructions.
  • Validation-first · quality criteria are part of the production path.
  • Human-accountable · automation reduces repetitive execution while human direction and final accountability remain explicit.

04

Tools.

Broad hands-on experience across the AI content production stack: I test platforms in real workflows, compare capabilities, identify limitations and select the right tool for each requirement.
