About Lilian

Hello 👋 I'm finally on Malt!

Marketing teams rarely have the technical profile to fully leverage their data. The result: untapped potential, decisions made on approximate data, and budgets allocated without really knowing what's performing.

No matter the title we want to give this role, data analyst, analytics engineer, tracking specialist, technical marketer... that's exactly where I come in!

🧩 Tracking & Measurement
Tagging audit and plan, GTM web and server-side implementation (Stape, Addingwell), analytics tool configuration (GA4, Amplitude...). Also advanced use cases: Offline conversion tracking (MQL, SQL), performance-based drive-to-store, margin-based steering, etc.

🏗️ Analytics Engineering
I centralize your data in BigQuery and model your business KPIs with Dataform or DBT. A single source of truth, clear rules, a solid foundation for everything that comes next: reporting, analysis, activation. Let's forget the 12 Excel files filled out by hand that contradict each other in meetings.

🔮 Data Analysis & Steering
LTV, acquisition cohorts, blended attribution to challenge your platforms, funnel analysis, steering dashboards on Looker Studio. Clear answers on what's really performing.

🛠️ Stack :
  • Tracking : GTM web & server-side, Stape, Addingwell
  • Analytics : GA4, Amplitude
  • Data Warehouse : BigQuery, Dataform, DBT
  • Dataviz : Looker Studio

6 years of experience including 2 years in a tech scale-up. More than 30 clients supported in marketing data consulting.

Let's discuss it, I'll quickly tell you if I can help you 😊
