• CASE_007 / SHOPIFY / UK / SKINCAREFIXED

  UK Shopify skincare brand

  Purchases fired twice on one checkout path and not at all on another, and a misconfigured consent gate silently dropped a third of the rest. I rebuilt the stream on server-side GTM with deduplicated event IDs, restored consent-blocked purchases, and reconciled events against Shopify order exports daily for 90 days before signing it off.

• CASE_011 / DTC COFFEE / DE / SUBSCRIPTIONFIXED

  Meta reported 4.1x ROAS. The P&L said 2.4x.

  Pixel and CAPI were both claiming every purchase, subscription renewals were counted as new orders, and nobody had reconciled the ad account against the ledger in a year. I rebuilt the event stream with shared event IDs, split renewals from acquisition, and rewrote the reporting on BigQuery so spend decisions run on numbers that survive an audit.

• CASE_014 / FIND SURFACES / UK / SHOPIFYBUILT

  One clean data layer feeding GA4, Meta, LinkedIn and Pinterest

  I built a Shopify data layer, rebuilt the GTM web container around it, and sent the full GA4 ecommerce funnel plus Meta, LinkedIn and Pinterest events through both the browser and the server. Internal traffic was filtered out of GA4 and every event was documented in a handover PDF.

• CASE_015 / DONATIONS / KSA / NON-PROFITBUILT

  Five ad platforms, one server container, every donation counted

  I set up GA4 and Google Ads alongside Meta, TikTok and Snapchat, with each ad platform receiving events from the browser and from a server-side GTM container. Every event carries a shared event ID so the platform can drop the duplicate, plus the click IDs and hashed customer data it needs for matching.

• CASE_016 / WIX / REAL ESTATE / LEAD GENBUILT

  Every lead logged with its source, straight into a Google Sheet

  I installed GTM and GA4 on Wix, wrote custom data layer events for all three forms and for copying the phone number, and kept first-touch UTMs in the browser. On every submission the lead and its source are sent to a Google Sheet through Apps Script, so the client has a simple CRM with attribution built in.
