Hey, I'm Sebastien. I fix broken Shopify analytics and help stores track their real numbers. You know that feeling when your Facebook Ads show 100 sales but Shopify only shows 70? Or when your analytics dropped 40% after iOS 14.5? That's what I solve. I've spent the last 3 years deep in the trenches of e-commerce analytics, working with everyone from €50K/month DTC brands to enterprise clients like Club Med and Sézane. My obsession? Making sure every single conversion gets tracked properly. What I actually do: - I implement server-side tracking that captures 99% of your conversions (most stores only get 60%). - Last year alone, I helped clients recover €1.2M in revenue they didn't even know they were missing. My sweet spot is Shopify stores doing €100K+ per month who are tired of: - Massive discrepancies between ad platforms and Shopify - iOS 14.5 destroying their Facebook tracking - Not knowing which ads actually drive revenue - Spending hours trying to reconcile different data sources Recent client results: - L'Arbre des Chakras: Implemented Elevar server-side, now tracking €300K/month accurately - 30+ Shopify stores: Improved attribution accuracy by 47% on average - Stride-Up portfolio: Cut BigQuery costs by 60% while processing 1M+ events daily Tech I work with daily: - GA4, GTM (client + server), Elevar, BigQuery, Looker Studio, Meta CAPI, TikTok Events API, Shopify Checkout Extensibility, Python for custom scripts How I work: I don't do basic GA4 installs. If you need someone to just add a tracking code, I'm not your guy. But if you want someone who'll dive deep into your data, find the gaps, and build a system that actually works? Let's talk. Fair warning: I'm direct about what's broken and what it'll take to fix it. But I also explain everything in plain English and make sure you understand what we're building. Next steps: Send me your store URL and tell me your biggest tracking headache. I'll take a quick look and let you know if I can help. Usually respond within a few hours (Paris time).
