What I Deliver

Growth & Conversion Analytics

I don't just run campaigns, I build the measurement systems that tell you what's actually working and how to fix issues on a recurrent basis. Here are some of my results delivered:

• 42% conversion increase through behavioral analytics and payment funnel optimization

• Sentiment-driven growth strategies

• Full-funnel tracking and attribution based on data

Best for: Companies spending on marketing but unsure what's driving results.

Financial Analytics & Reporting

Investor-ready financials, automated. I've built reporting systems for global commodity trading, PE-backed SMEs, and EU institutions.
