About Julien

I help e-commerce businesses to make their tracking reliable and optimize their Meta/Google Ads campaigns.
Fast, efficient, and ROI-oriented interventions: I enjoy solving concrete problems that hinder performance.

Do you need to:
  • Set up reliable tracking (GA4, Meta Pixel, Conversion API, GTM, Server-Side Tracking)

  • Launch or optimize Meta / Google Ads campaigns
  • Fix a conversion tracking issue
  • Audit your Ads and identify quick wins
This is exactly what I do for e-commerce brands with €50k to €300k/month in revenue.

I don't sell "community management" or vague promises:

  • My goal is to quickly solve a specific problem
  • You leave with a clean, functional, and measurable system
  • I prefer short and concrete missions (1 to 5 days max)

Examples of missions completed

GA4 + GTM setup for a Shopify site → functional tracking in 48h

Complete Server-Side Conversion setup + event testing → +30% reliability in tracked conversions

Meta Ads account audit → identification of 3 quick wins = ROAS x1.6 in 30 days

Creation of an optimized Google Ads Search + Shopping structure → CPA decrease of 22%

Why work with me?

âś… 7+ years of experience in e-commerce media buying
âś… DTC specialization (fashion, skincare, food, lifestyle)
âś… Pragmatic approach: you call me, I fix the problem, you leave with a system that runs
âś… Simple, clear communication, without unnecessary jargon

Indicative pricing
  • Tracking mission (pixel, API, GA4, GTM): from €400
  • Meta/Google Ads campaign setup: from €600
  • Ads audit & strategic recommendations: from €500
(I adapt based on complexity and requested deadline.)

Contact me directly with your current issue (tracking, Ads, or funnel): I'll give you a free initial feedback within 24 hours and we'll see if I can help you quickly.
