Performance Marketing Manager at Advengers, reducing CAC 15% with automated search-query analysis.

Greece
Message

At Advengers, I own paid acquisition strategy across ecommerce and lead-generation accounts, working across Google Search, Shopping, Performance Max, YouTube and Meta. I developed automated search-query analysis using n-gram methodology, reducing CAC by 15% across selected accounts.

I also build testing roadmaps and media plans around commercial objectives, seasonality and performance. In selected implementations, piloting Google AI Max contributed to a 10% reduction in CPC and a 15% increase in ROAS.

At T&P, I managed more than €6M in annual paid media investment across international B2C and lead-generation accounts. Structured testing across creatives, audiences, bidding and landing pages drove a 20% reduction in CPA and month-over-month efficiency gains.

At Mindshare Greece, I developed integrated media strategies and managed Google and Meta acquisition campaigns for B2C brands. I studied Business Administration (Marketing) at the University of Kent and Social Sciences at the University of Glasgow.
