I’m Laurent Fidahoussen, a freelance tracking and analytics consultant based in Paris. FASilytics has been my business since September 2025.
My job: making sure your numbers are right. When GA4, Adobe Analytics, Google Ads and Meta don’t tell the same story, I find out why and fix it.
My background
| Period | Where | Role |
|---|---|---|
| 2025 – present | FASilytics (freelance) | Tracking, analytics, ad data, consent |
| 2023 – 2025 | American Express GBT | Sr Lead Analytics & Tracking |
| 2019 – 2022 | Expedia Group | Lead Analytics & Tracking (Adobe), US, France and India teams |
| 2017 – 2019 | TheFork (a Tripadvisor company) | Lead Analytics & Tracking |
| 2015 – 2017 | SFR | Lead Analytics & Tracking |
| 2002 – 2015 | SFR, Poweo, Parship… | Software engineer, then technical project owner |
That developer background matters: I read tag and app code like a developer, and explain it to a marketing director.
What I do
- Analytics audits and fixes (GA4, Adobe Analytics)
- Consent Mode v2 and multi-market CMPs (Didomi, Tarte au Citron)
- Tagging plans, Commanders Act and server-side tracking
- Hybrid app tracking (Firebase, AppsFlyer) and data for Google Ads and Meta
