Expert Looker Studio (Google certified) | GTM Server-Side Tracking.
Are your data scattered, your tracking unreliable, your dashboards not used for decision-making?
I build the data infrastructure that enables your marketing team to make decisions in 15 minutes instead of 4 hours — with reliable, centralized, and understandable figures.
→ +100 SMEs/Mid-sized companies supported: Laboratoires URGO, Okamac, TchaoTchao (QVEMA), Embarq, Worldia, Namastrip, Charlotte K, Leverage, OTO Agency, Klaro, Flakon…
→ Former Head of Growth turned marketing data expert — more business-minded than data analysts, more data-driven than agencies
→ Certified Google Coach (Data Analytics, GA4, GTM, Looker Studio)
→ +7 years in tracking, dashboards, and data analysis
Do these phrases resonate with you?
"We no longer trust our numbers."
"The board is asking for marketing ROI and we don't know how to answer."
"We have GA4 but no one really uses it."
My approach: 4 layers, from tracking to decision-making
1. Reliable tracking —GTMAudit, tagging plan, client-side + server-side setup (Stape, **Addingwell**), **Consent Mode V2**.
2. Centralization — Google Sheets x Supermetrics or BigQuery **Data warehouse**, multi-source connection (Meta, Google, TikTok, Bing, Klaviyo, CRM).
3. PilotDashboards— Decision-oriented **Looker Studio**, team training for autonomy.
4. Strategic Analysis — **Multi-touch attribution**, creative performance, customer segmentation, growth recommendations.
Why not a traditional freelancer?
I work with my Data Detective team (Greg-Jordan, Senior Web Analyst + Alexandre, Data Engineer) — guaranteed continuity, full-stack vision, structured process.
Who I target
E-commerce and DNVB brands (€2M-€120M turnover, Paid budget +€10K/month) looking to manage their multi-channel ROAS (Meta, Google, TikTok, Bing, Klaviyo) from a single, reliable Looker Studio dashboard.

Experience
- CobraBigQuery & Custom Dashboard Data Warehouse ArchitectRETAIL (SMALL BUSINESS)March 2026 - May 2026 (2 months)Cobra is an audio/hi-fi equipment distributor. Before the project, purchasing activities were managed through manual and incomplete Odoo exports, lacking a unified single source of truth for 7 key indicator blocks (inventory, suppliers, margins, cash flow, etc.).First deployment of the Data Detective AI Partner offering: we no longer deliver a dashboard, we build the data stack that makes self-service a reality (governed warehouse + multiple interfaces on top).Layer 1 - BigQuery Data Warehouse as the single source of truth. Odoo 18 connected as a source, models audited via Odoo API and fields_get, star schema modeling (dimensions + facts). Business definitions documented. ~60% of the project effort.Layer 2 - Custom HTML Dashboard directly connected to BigQuery, written with an AI agent. No licensed BI tools, no design limitations, each indicator calibrated to Cobra's purchasing needs.Layer 3 - Conversational layer via MCP (Model Context Protocol) + official Google BigQuery MCP server. The purchasing manager asks their question in French, the AI agent queries BigQuery and returns a synthesized answer.Stack: Odoo 18, Odoo API, BigQuery (star schema), Custom HTML Dashboard, MCP, AI Agent.Results: 7 unified indicator blocks, 1 BigQuery warehouse as the single source of truth, 2 query interfaces (custom dashboard + conversational agent), elimination of reliance on manual Odoo exports.

I've worked with many data professionals over the years, and Robin is undoubtedly the best I've encountered.
Beyond his sharp technical skills in Google Analytics 4, Looker Studio, and Google Tag Manager, what sets Robin apart is his ability to consistently go beyond the initial scope. He doesn't just deliver what's asked; he anticipates needs, suggests optimizations, and ensures every tracking element is perfectly configured.
His expertise in data marketing and server-side implementation has provided us with reliable and actionable data. Implementing Supermetrics to centralize our reporting has transformed how we manage our campaigns.
A true data analyst who understands business challenges, not just technical aspects. I recommend him without any hesitation.

Robin conducted a comprehensive tracking audit (client-side and server-side GTM tracking) and developed a personalized Looker Studio dashboard that consolidates all Paid Media performance (SEA, SMA, Meta Ads, affiliate).
His tracking audit precisely identified critical bugs. Very constructive and pedagogical, he collaborated closely with my agency to fix them.
On the data analysis and web analytics side, his expertise in GA4 and data-driven marketing enriched his questioning about my reporting needs. He delivered an intuitive and actionable Looker Studio dashboard (integrating SuperMetrics for ad platforms). His solid experience in digital marketing and growth marketing allows him to challenge results to ensure data reliability. I now have a serious tool to manage my SEA, Social Ads, Meta Ads, and affiliate campaigns, with a clear view of ROI and opportunities.
Robin is also exemplary in communication: from understanding needs to mission delivery, including explanatory videos, flexible video calls, always friendly and professional. He keeps his commitments and goes beyond by revealing data-driven opportunities and best practices.
I highly recommend him to anyone looking for a freelance expert in GTM/GA4 tracking, server-side tracking audit, Looker Studio dashboards, and Paid Media performance analysis!
