PDS Shop — Closing the 30% Gap Between Shopify and Google Ads with Stape.io

A French online perfumery on Shopify was looking at a 30% gap between the transactions logged in their Shopify admin and the conversions reported by GA4 and Google Ads — every day, growing wider every quarter. We deployed server-side tracking via Stape.io, layered CAPI on top of the existing pixels, and closed the gap to under 5% within three weeks.

Hertz Maroc — Rescuing a Botched Server-Side Migration with dbt

A previous agency migrated Hertz Maroc to server-side tracking and Consent Mode V2 — and broke two years of Power BI reporting in the process. The migration renamed every funnel event to Google's recommended schema without accounting for the GA4 → BigQuery → Power BI pipeline, and shipped a consent banner that left dismissed sessions in an undefined state. We rebuilt the foundation with a dbt reconciliation layer and a properly configured consent flow.

Prestigia.com — Rebuilding the Data & Activation Stack of a Premium OTA

A premium online travel agency selling primarily into the US market had a fundamentally broken tracking stack — Firebase reporting wrong conversion values, a 140-tag GTM container firing false data, and no real funnel visibility. We rebuilt the foundation: business-grade datalayer, server-side tracking, BigQuery warehouse, and a Klaviyo-driven retention engine.
