Acerca de Simon
Who am I?
I'm a Media Buyer with 5+ years of experience in paid acquisition and performance marketing, working both agency-side and in-house. I help brands build, scale, and optimize profitable campaigns across Meta Ads, Google Ads and TikTok Ads, as well as native and metasearch platforms (Taboola, PropellerAds, Trivago, Kayak).
I don't just run campaigns — I own the full funnel, from strategy and advanced tracking to creative testing, data analysis, and scaling toward real business results: sales and revenue, not vanity metrics.
Track record
✅ Hands-on ownership of €1M+ monthly ad budgets on Google and Meta
✅ Scaled a single account from €50K to €400K/month while holding target ROAS
✅ 12x ROAS on Brand and 3x on non-Brand campaigns (average)
✅ 100K+ qualified leads generated per month across portfolios
✅ Managed 45+ ad accounts across Education, Real Estate, Automotive, Insurance, E-commerce and more
✅ Built a proprietary Automated Creative Testing framework (Python + Meta Graph API) to mass-test video creatives at scale
✅ Automated reporting and lead management end-to-end — freeing ~2,000 hours/year for higher-value work
✅ Designed a custom ROAS-driven bidding model (still in production), hitting 854% ROAS vs a 900% target in week one
Beyond campaigns
I build my own tools. I'm currently developing Hektor, a SaaS for automated Meta Ads management — rule-based optimization engine, performance dashboard, and AI-generated ad copy. That same engineering mindset (automation, clean tracking, data-driven decisions) is what I bring to every account I touch.
Why work with me?
You get a senior operator who thinks like a growth partner: autonomous, accountable to revenue, and focused on what happens after the click. I work in French (native), English and Spanish, across European and international markets.
Let's scale something.
