GA4 · Google Tag Manager · Consent Mode v2
Tracking that holds up when you check it.
I'm Mateusz, a Google Analytics certified specialist. I set up, audit and fix GA4, Google Tag Manager, consent and conversion tracking, and I build the dashboards that sit on top of it.
What I work on
GA4 and GTM setup and audits
Events, conversions and cross-domain tracking, in a container that stays easy to maintain.
Ecommerce tracking
The full purchase funnel for Shopify and WooCommerce, from product view to purchase, with revenue you can reconcile.
Consent Mode v2
Consent that works with your CMP, tested before and after the visitor makes a choice.
Ad conversion tracking
Google Ads with Enhanced Conversions, plus Meta, TikTok, LinkedIn and Microsoft Ads from one GTM container.
Server-side tracking
Server-side GTM on Stape with the Meta Conversions API, deduplicated against the browser pixel.
Dashboards and reporting
Looker Studio and Power BI dashboards, GA4 exports to BigQuery and automated data pipelines in n8n.
How I work
Everything happens in writing. Before I start you get a clear plan, and I test every change before I call it done. I take a project from audit to handover and don't leave it half finished. Project documents, from the first plan to the final report, wait for you in a private client area on this site, behind your own password.
