Hi there!

The first ‘grown-up’ book I ever read was Marley & Me, when I was nine. My favourite sound is actors shuffling papers in films. I can't watch a concert without crying, mostly from the collective euphoria, because I love people.

‍

Now that we've broken the ice, let's talk about my more corporate side: I've been a copywriter for six years. I know advertising can be intrusive and, all too often, a nuisance. So, from the brief to the final report, I've always championed doing things differently. Making it more than just tolerable: fun, moving, exhilarating, thought-provoking. Throughout my career, I've put that belief into practice with some of the biggest brands in the business.


At Agência SoWhat, named Agency of the Year at the TikTok Ad Awards 2025, I was creative lead of a team of eight copywriters and art directors. Alongside the creative director, I led the creative and strategic work for O Boticário and Colorama. I developed campaigns, PR stunts, branding strategies and culture-first creative strategies for O Boticário, Eudora, Schutz, Hope, Arezzo and Colorama, among other fashion and beauty brands. Each, in its own way, brought a human touch to advertising and won over audiences through the culture, entertainment and relevance that give things more flavour and make them more interesting.


That approach has earned my work two Effie Awards, one MMA Smarties Award, a bronze at CCSP and more than five TikTok Ad Awards.


I do what I do because I'm also an author. Editora Patuá published me in 2023, and my first book launched at FLIP that same year. In everything, from a note on a napkin to a campaign that makes you smile or an award-winning strategy, I believe in the power of writing the way you kiss: with intention.
