AI marketing systems that make better decisions scalable.

The connected system

From traffic to qualified lead, every handoff matters.

Acquisition, landing pages, capture, CRM, nurture, and follow-up are often managed as separate jobs. I see them as one connected system, because a weak handoff can undo the work that came before it.

Career progression

Built across the whole path, one chapter at a time.

My perspective comes from working across the connected system, from attracting attention to making the systems behind marketing run properly.

  1. 01
    Acquisition and websites

    Learning how attention becomes action

    I worked hands-on across websites, SEO, paid acquisition, and e-commerce with TantoMarketing, TEFANESO, Mondaine, and Simply Jet.

  2. 02
    MarTech and CRM operations

    Connecting campaigns to the systems behind them

    At Flyability, my work moved deeper into marketing operations, HubSpot, Salesforce, automation, analytics, and the handoffs between the website and CRM.

  3. 03
    AI-assisted growth systems

    Making the complete path more strategic

    Today, my consulting work brings those chapters together through practical AI agents that support better marketing decisions, not simply more output.

The person behind the systems

Venezuelan roots, a Swiss base, and an operator’s point of view.

I’m a founder and marketing operator based in Switzerland, working in English and Spanish. My Venezuelan background, entrepreneurial experience, and years inside different marketing teams have shaped a practical way of solving problems.

I like getting close enough to the work to understand what is really happening, then connecting strategy, systems, and execution into something people can use.
