Background & Approach
From Berlin to Buenos Aires
With a background in Economics and Linguistics, I've spent over two decades working at the intersection of language, technology, and market strategy.
Before focusing on Semantic SEO, I spent 15+ years in content localization – working with organizations like the Konrad-Adenauer-Stiftung, Counter Extremism Project, universities, and international brands across Europe and Latin America. This foundation in cross-cultural meaning transfer now informs my approach to AI visibility and semantic search.
Born in Berlin and based in Argentina, I bridge European precision with Latin American perspective — a combination that informs my approach to international SEO and cultural localization.
Core Focus Areas
- International SEO & Cultural Localization — Meaning-based strategy, not just translation
- AI Visibility & Knowledge Graphs — Ensuring brands are recognized by ChatGPT, Perplexity, Gemini
- Semantic Content Architecture — Structured information that machines and humans understand alike

Where Theory Meets Practice
My approach to semantic SEO is grounded in hands-on work with language and culture.
MundoDELE
Spanish language education and intercultural competence. This is where I test semantic localization concepts in practice — working daily with how meaning shifts across languages, how cultural context shapes understanding, and how people actually learn to navigate between linguistic worldviews.
Teaching language reinforces what I know about international SEO: successful cross-cultural communication isn't about translation, it's about understanding how meaning is constructed and perceived differently across cultures.
