About Joanna

I'm a social media and content strategist with a knack for disruptive creativity. I’ve led global strategies, built teams from scratch, and launched viral campaigns - including a Ford tech demo that earned a D&AD Wood Pencil, and generated 4.4 billion organic impressions. Yep, all organic.

At Criteo (ad tech), I built the brand’s entire social media ecosystem from the ground up. From team setup to a Super Bowl campaign, I delivered strategies that connected, driving 42% YoY engagement growth.

Before that, I led social at agency C14 (DDB) for SEAT and CUPRA, managing product launches and partnerships with FC Barcelona and Primavera Sound in one of the most competitive spaces: the automotive industry.

Why work with me?
→ I help brands show up with purpose, not just presence.
→ I bridge strategy and storytelling to create content that connects and converts.
→ I speak both human and algorithm, creating work that performs on platforms and resonates with people.
→ Organic, paid, evergreen, or reactive... You name it. I build ecosystems where every piece of content has a job to do.
→ I bring tangible results: 42% YoY engagement growth. 4.4B organic impressions. One viral Ford campaign, and a D&AD award to match.
