What I can do for you

From tracking that actually works to data that tells you something — freelance missions via OnTrust. 20 years of fieldwork, not slides. From operational to strategic, calibrated to your context.

I work with advertisers, media agencies and publishers. Sometimes it's a one-off audit, sometimes it's a 2-year engagement. The format depends on what you need to solve.

Tracking & Ad Operations

Your tracking isn't reporting correctly, your naming conventions are a patchwork, your campaigns go live late — these are the kinds of problems I solve. From audit to production, including the troubleshooting.

  • Existing setup audit: I assess what you have, identify what's broken, and tell you what to fix first
  • Naming conventions: taxonomies that hold up when you scale to 10 countries and 5 platforms
  • Setup & trafficking: campaign launches on DCM, DV360, Meta, LinkedIn, GAM — or your other adserving and buying platforms
  • Quality control: creative verification (technical specs compliance), data verification, discrepancy detection — one misconfigured tag or non-compliant format corrupts the entire reporting chain
  • Tag management: inventory, audit and rationalization (I managed 3,700+ tags for Blizzard EMEA)

Media agencies, advertisers with international campaigns, teams in transition or needing reinforcement.

AXA GIE: Implementation of a single Media Plan template for global campaigns, deployed across 30+ entities.

Data Management & ETL

Your media data is scattered across 6 platforms and 3 Excel files. Reporting arrives at the end of the campaign, too late to act. I centralize, connect, and automate.

  • ETL migration: replacing outdated systems with modern solutions (Adverity, Funnel, Supermetrics)
  • Source connection: API integration of your platforms (Meta, Google, TTD, IAS, Piano...) — I connected 6 simultaneously at AXA
  • Matching & reconciliation: naming conventions defined upstream feed directly into automated matching downstream
  • Reporting automation: daily reprocessing, alerts, dashboards. No more end-of-campaign reporting.
  • Multi-source consolidation: aggregation of data across all media channels for econometric studies

Advertisers with fragmented reporting, agencies in centralization phase, data teams looking to industrialize.

AXA GIE: Migration from Reeport to Adverity. Weekly monitoring instead of end-of-campaign reporting. 100% of placements matched automatically.

Analytics & Reporting

Data is useless if nobody looks at it — or nobody understands it. I set up the measurement tools, build the dashboards, and make sure privacy compliance is in order.

  • GA4 migration: event and goal configuration — not just a copy-paste of the old setup
  • Piano Analytics: presentation writing and project management (AT Internet)
  • Dashboards: Looker Studio with audience segment integration — dashboards people actually use
  • Consent Mode V2 & GDPR consulting: compliance support, OneTrust monitoring — privacy isn't just a legal issue, it's a technical one
  • Ad Verification: IAS / DoubleVerify setup and management (viewability, brand safety, fraud detection)
  • Innovation: Server-to-Server workshops, CAPI (Meta, Google), Privacy Sandbox

Advertisers in analytics migration, groups with 10+ entities, teams preparing for the end of third-party cookies.

AXA GIE: Analytics support for 30+ entities, centralized license management, innovation workshops on S2S/CAPI/Privacy Sandbox.

Publisher Monetization

You have traffic and you want to monetize it intelligently. Not just slapping on banners — designing an inventory architecture, finding the right pricing, maximizing fill rate without sacrificing user experience.

  • Monetization strategy: direct deals, programmatic, or both — the answer depends on your positioning, not what's trendy
  • Google Ad Manager setup: full configuration (Ad Units, Key-Values, targeting, passbacks)
  • Yield Management: floor pricing, A/B testing, fill rate optimization
  • Ad Exchange integration: Google AdExchange activation and configuration, header bidding
  • Operational management: campaign trafficking, creative adaptation, delivery monitoring
  • Partner benchmarking: A/B testing Taboola, Criteo, Sublime Skin, Adikteev — actual CPMs, not sales brochures

Online publishers and media, federations and institutions, high-traffic websites.

FEI: 3 sites, 1.5M impressions, direct deals, 4+ years. Le 10 Sport: 40-50M impressions/month, 10-30k EUR/month, ecosystem built from scratch.

Team Training & Enablement

Your teams need to level up on tracking, ad ops or analytics. Or you need someone to hold the fort until you hire. Either way, I've done it.

  • Tracking & ad ops training: hands-on sessions using real tools, with focus on improving template usage
  • Analytics upskilling: GA4, Adverity, Looker Studio training tailored to your context
  • Documentation & processes: playbooks, workflows, technical specs
  • Transition management: I take over while you recruit (done at IPG, AXA)
  • Offshore support: training and monitoring of remote teams (3 years of experience with teams in India)

Agencies in structuring phase, advertisers with offshore teams, organizations in transition.
