MANIFESTO & EXECUTIVE PROFILE

Digital product strategy with analytical precision and commercial vision.

As a Digital Product & UI Designer, I combine rigorous training in interface architecture, design systems, and product methodologies (Advanced Figma, Platzi & Torresburriel Estudio) with hands-on commercial and operational leadership. I craft clean user flows, high-fidelity interactive prototypes, and production-ready design systems.

My experience coordinating cross-border operations, SEO optimization, and e-commerce logistics gives me a strategic competitive edge: I build interfaces governed by real customer data, Google Search Console indexing, GA4 behavioral analytics, and net conversion rate optimization (CRO), aligning every visual decision with business profitability.
