About me
I’m a senior creative based in Madrid, working across Europe at VML Madrid (Studio X) for The Coca-Cola Company.
My work lives where culture, platforms and behaviour meet — building ideas that people want to engage with, not ads they want to skip.

FAQs

Brands don’t compete for attention anymore; they compete for relevance.
I approach storytelling by creating ideas that behave like culture, not like ads. That means understanding how people consume, remix, and share content, then building narratives that feel native to those behaviors.
If the idea doesn’t earn its place in someone’s feed, conversation or routine, it doesn’t deserve to exist.

I foster innovation by encouraging experimentation, embracing failure as learning, and pushing creative boundaries. A culture of collaboration and curiosity keeps ideas fresh, while structured rapid prototyping helps validate risks efficiently.

Being a gamer, I approach brand storytelling with player-first thinking. I see endless potential for brands. AI-driven characters, immersive narratives, and branded game hacks will redefine engagement.
