Rebuilding tracking and checkout, single-handed
A full tracking rebuild with Consent Mode v2 for an automotive repair network, followed by structured tests on the mobile checkout.

Context
Most bookings started on mobile, but the client could not see where the checkout lost people, and consent handling did not meet GDPR Consent Mode v2.
What I did
- Audited the existing setup, then architected and deployed end-to-end tracking: GA4, GTM, CookieYes CMP and Google Ads conversions, with Consent Mode v2.
- Built GA4 funnel events and dashboards for the checkout funnel, form drop-offs and navigation.
- Ran journey analysis and heatmapping, then structured A/B tests on the checkout.
- Documented the stack in Notion so the team could self-serve.
Outcome
- Mobile conversion up 20–25%.
- Compliant consent handling and conversion data the team could read without help.
