Five-plus years across international startups in the US, Argentina, Mexico and Paraguay. I've been the first engineer more than once — the person who turns a founder's whiteboard into a system real users depend on.

Today I combine product strategy with hands-on execution as Entrepreneur in Residence at InzaiQ, validating AI-native products from discovery to delivery.

(03)Capabilities

A rare overlap: deep applied-AI experience, full-stack craft, and the product instincts of someone who has been an early engineer again and again.

Applied AI

LLM features that survive real users.

Conversational bots, retrieval pipelines and agents wired into real workflows — in production since 2022.

Product & Strategy

Founder-minded execution.

Discovery, scoping and architecture with non-technical stakeholders — then rapid MVPs that iterate on feedback.

(04)Experience

    • Building and validating AI-native products across client engagements — including a real-estate tokenization platform (ERC-3643 / Polygon) and internal AI tooling for operations and reporting.
    • Owning end-to-end execution: discovery and scoping, architecture, LLM integration and delivery to non-technical stakeholders.
    • Rapid-prototyping MVPs and iterating on client feedback as both product and engineering lead.
