Senior Full-Stack Performance Marketer · 10+ years experience
Performance marketing done right. From day one.
10+ years of experience. 100+ clients. From startups to global brands, across B2B and e-commerce. I've built, optimized and scaled performance marketing setups, working directly with businesses and as a senior specialist for agencies. I know where to find opportunities, what holds performance back and what actually moves the needle.
I personally handle the entire stack: Google Ads, Meta, LinkedIn and Microsoft Ads, plus the technical foundation behind them. GTM, GA4, conversion tracking, CRM integrations, reporting and automation. From strategy to execution, without the layers in between.
I read everything myself. Usually reply within a day.

The full performance marketing stack.
