About
Performance marketer, digital storyteller
I'm a data-driven paid social expert and digital storyteller, specialised in Meta, TikTok, LinkedIn and Snapchat. I manage budgets from €1K to over €1M and I'm happiest where creative and numbers meet: testing hooks, reading the lift study, then putting the spend where it works.
I'm passionate about partnering with ambitious brands ready to grow, as a freelancer or as an extension of your agency team.

Domino's France: measuring incremental purchases with a Conversion Lift Study
A TikTok Top View campaign, measured against a randomised control group, to prove how much incremental revenue the channel actually drives. The study was then replicated in Belgium, the Netherlands and Germany.

Secret Pizza Germany
For our German market I initiated an exclusive campaign for TikTok.
With the help of our team at TikTok and the German team, we created a secret pizza. The pizza was a smashed burger, a concept that was turning into a hype, and we hid it away in our menu. Our pizza wasn't the secret, but how to get it was.
With the help of 100 micro creators, divided into different phases, we launched this project on TikTok only.
A CRO-optimised landing page
Designed and built as a conversion exercise: one page, one decision. Never shipped, so there is no result to report, only the reasoning.
One call to action, repeated. No competing links to leak attention.
Offer and proof above the fold, objections handled in the order visitors raise them.
Form friction stripped to the fields that are actually used.
Content for client socials
UGC-styled video and static creative, made for TikTok, Meta and YouTube.
Static carousel: Silver Tie at Waregem Koerse
Four slides carrying one story: the scale of the event, the single point of contact, the client's words, and the call to action.

Five years of paid media, in order
