What I work on

The whole tracking and analytics stack, end to end.

Analytics and reporting

GA4, BigQuery, Looker Studio (Data Studio), Mixpanel, Power BI and Adobe Analytics: clean data, dashboards your team trusts, and straight answers to questions like which channel really drives sales.

Tag management

Google Tag Manager, Tealium, Adobe Launch, Segment and RudderStack, plus custom code on Shopify, Webflow and WordPress sites when the setup needs it.

Server-side tracking

Server-side Google Tag Manager on Stape (I’m a Stape partner), Google Cloud, AWS and TAGGRS, plus Shopify tracking apps like Elevar and Fueled.

Ad platform conversions

Google Ads, Meta, TikTok, Pinterest, Microsoft, LinkedIn, Reddit, Snapchat, X and StackAdapt: enhanced, offline and server-side conversions, including Google’s Data Manager API.

Ecommerce, feeds and subscriptions

Shopify (Liquid, headless Hydrogen and Custom Pixels), WooCommerce, Chargebee, Google Merchant Center and Meta catalogs, so products and purchases line up everywhere.

CRM and email

HubSpot, Salesforce and Pardot, GoHighLevel, Zoho, Klaviyo and Attentive, connected to your ads directly or through Zapier, so platforms learn from real customers.

Phone call tracking

CallRail and CallTrackingMetrics, with calls sent to Google Ads, GA4 and your CRM as real conversions.

Consent and privacy

Cookiebot, OneTrust, TrueVault and TrustArc set up so tracking respects consent without quietly switching off.

Booking and affiliates

Calendly, Zenoti and Mindbody tracking, plus affiliate networks like AWIN and Partner Ads.

What clients say

5-star reviews from Upwork clients.

Real reviews from my Upwork profile, quoted as written.

★★★★★
“Other clients should know that John doesn’t just install tracking — he thinks in systems. … When something is off, he doesn’t guess. He audits, isolates variables, and fixes root causes. That’s rare.”
