About Me

I'm a Performance Marketing Expert with 7+ years of experience bridging strategic vision with precise technical execution — managing the full picture from P&L to pixel-level campaign structure.

My work spans E-commerce, Financial Education, Digital Fashion, and Luxury Brand Strategy. I've scaled budgets up to €15k/month while maintaining strict profitability, and I don't consider a campaign successful until the numbers prove it.

Based in Lyon, France. Available remotely, globally. Fluent in English, Greek, French, and German.
