I’m Alex McLean, a digital analytics implementation specialist with 20 years’ experience across tagging and measurement—from requirements and technical specifications to debugging, testing and data QA, all the way through to analysis, insights, reporting and dashboarding. I’ve worked extensively with tag management systems (including Google Tag Manager, Adobe DTM, Adobe Launch and Tealium) and major measurement platforms such as GA4, Adobe Analytics, Google Ads and Looker Studio, helping teams turn complex tracking requirements into reliable, actionable data. I’m equally comfortable deep in the technical details (JavaScript, HTML, DOM, dataLayer work and QA) and advising stakeholders on what to measure and why. Across a wide range of sectors, I’ve delivered GA4 migrations, ecommerce and consent-mode implementations, and third-party marketing pixel integrations (including Meta CAPI, TikTok CAPI, Amazon DSP and email/SMS vendors), ensuring governance and consistency while improving campaign and event tracking quality.
