About me

Paid Social & Performance Marketing specialist for e-commerce, marketplace and retail across CEE markets (PL, DE, CZ, HU, RO, AT, SK, UA). I run campaigns to hard business goals - primarily ERS, plus ROAS, CPA and CR - and pair paid-media execution with data analytics.

Meta Ads and Google Ads (Search, PMax, DSA, Demand Gen), plus TikTok, YouTube and DV360 - from account audits and pre-launch QA to scaling and reporting (GA4, Looker Studio).

What I do best: ad account audits, campaign restructuring, budget reallocation to winners, real profitability after returns (gross-to-net), brand/PMax cannibalization tests, URL/UTM discipline, product feeds and placements.

I also automate reporting - e.g. Google Sheets dashboards pulling live data from the Meta Marketing API via Apps Script, with no paid connectors.

What sets me apart: operational rigor, fast measurable decisions and turning data into clear budget calls under tight deadlines.
