Your ads are only as good as the data feeding them. I fix the data. I'm a GA4/GTM tracking engineer with a developer background: 115 Upwork projects, 6,000+ hours, Top Rated Plus. I build and repair the tracking layer that decides whether your ad budget scales or burns: GA4, Google Tag Manager, server-side GTM, Consent Mode v2, Meta CAPI, and Google Ads conversions. Results clients paid for and kept: - Recovered 15-40% of conversions lost to Consent Mode misconfiguration - Cut GA4 event duplication by up to 60% with clean dataLayer architecture - Raised attribution accuracy with server-side conversion APIs for Google, Meta, LinkedIn, and Reddit - Turned hours of manual reporting into minutes with Looker Studio dashboards teams actually open What I handle end to end: - GA4 + GTM: events, ecommerce funnels, custom dimensions, cross-domain tracking - Google Ads conversion tracking and enhanced conversions - Meta Pixel + Conversion API with deduplication and event-quality checks - Consent Mode v2 and GDPR/CMP setups: Cookiebot, OneTrust, custom banners - Server-side GTM for cleaner data and stronger attribution - Shopify, WooCommerce, WordPress, Webflow, Framer, and custom JavaScript tracking - Looker Studio dashboards your team can actually use Why me and not another GTM freelancer: most can click together basic tags. I read source code, inspect the dataLayer, and debug JavaScript - so the tracking I build survives redesigns, plugin updates, and CMS migrations instead of breaking a month later. Top Rated Plus | $100K+ earned | 6,000+ hours | 115 jobs completed How we start: send me your site, ad platforms, and tracking goal. I will map your funnel and tell you exactly what is broken, what is missing, and what it takes to fix it - before you commit to anything.

Your ad platforms, GA4 and your back office almost never agree on how many conversions you had. I make them agree โ€” and keep them agreeing after the next iOS update, cookie banner or theme redesign. I work full time as a digital analyst at a performance marketing agency, and I do the same thing here: conversion tracking that survives real-world conditions, and reporting people actually open. What clients bring me: ๐ŸŽฏ Ecommerce tracking rebuilt at the source โ€” Shopify Customer Events / Web Pixels custom pixel, checkout and order-status coverage, consent-gated events, plus WooCommerce and custom stacks. Not an app that half-works. โš™๏ธ Server-side tracking with Stape (sGTM) โ€” custom tracking domain, first-party cookies, Meta Conversions API with event_id deduplication between browser and server, Google Ads Enhanced Conversions, and TikTok, LinkedIn or Microsoft where the case calls for it. ๐Ÿ›ก๏ธ Consent Mode v2 and GDPR-safe measurement โ€” no tags firing before consent, ad_user_data and ad_personalization wired correctly, Cookiebot, OneTrust, Consentmo or a custom banner, tested in both granted and denied scenarios. ๐Ÿ“Š Reporting people actually use โ€” Looker Studio, GA4 export to BigQuery, and custom BI dashboards I build in Next.js straight from a warehouse, so a whole marketing month fits on one screen. ๐Ÿ”„ Automation โ€” n8n pipelines that pull your marketing and sales APIs into one always-current PostgreSQL warehouse, with retries, deduplication and replay-safe backfills. Recent work: - Shopify tracking rebuild: custom Web Pixels pixel plus theme dataLayer gap events, full GA4 ecommerce funnel (view_item, add_to_cart, begin_checkout, purchase), Consent Mode v2 gating, verified end to end. - Google Ads Enhanced Conversions with Advanced Consent Mode: user-provided data captured, validated and sent only when ad_storage and ad_user_data are granted. - WooCommerce enhanced ecommerce: the complete purchase funnel through GTM, with custom dataLayer variables and JavaScript for transaction and product data. - Multi-platform conversion tracking in GTM for Meta, LinkedIn and Microsoft Ads, with consent-aware triggers and consistent revenue parameters across channels. - Marketing data warehouse: n8n ingestion from five APIs into PostgreSQL with error handling and backfills, surfaced in a custom Next.js dashboard. Why me: - I do this every working day in-house, not as a side skill. - Every project I have finished on Upwork is rated 5.0, with written recommendations from clients. - Nothing is handed over unverified: GTM Preview, GA4 DebugView, Events Manager and request payloads for tracking; test runs and logs for automations. - You get documentation of what was done and why, and you own every account and container. No black boxes. How we start: send me your site, your ad platforms and the one number you don't trust. I'll map how your data flows today and tell you exactly what is broken, what is missing and what it takes to fix it โ€” before you commit to anything.

I build end-to-end customer data infrastructureโ€”from tracking through data warehousing, modeling, and reporting. Hi โ€” Iโ€™m Mac. I help companies design, build, and scale customer data infrastructure that actually works in production. That means: - clean, reliable tracking - a proper customer data platform - a well-modeled warehouse - and data that marketing, product, and leadership can actually use I donโ€™t โ€œjust set up GA4โ€ or โ€œjust deploy a CDPโ€. I build the full pipeline โ€” from first event to board-level metrics. What I actually do (end to end) 1. Tracking & data collection (web + mobile) - I design and implement production-grade tracking, not fragile setups. Typical work: - Client-side & server-side tracking (GTM, GTM Server, Snowplow, Segment) - Event taxonomy & tracking plans aligned to business metrics - Identity resolution (anonymous โ†’ user โ†’ account) - Consent-aware, privacy-ready setups (first-party focus) - Mobile tracking & attribution (AppsFlyer, SKAdNetwork constraints) Used when you need: - trustworthy funnel data - accurate paid attribution - fewer โ€œwhy donโ€™t these numbers match?โ€ conversations 2. Customer Data Platforms (CDP) I help you choose, deploy, and operate the right CDP โ€” or replace an expensive one. Hands-on experience with: - Snowplow (AWS / GCP, batch & streaming) - Segment (Protocols, Personas, hybrid Snowplow setups) - RudderStack - GTM Server as a lightweight CDP layer Use cases Iโ€™ve delivered: - syncing first-party data across 50+ sites - reducing CDP costs by 3ร— with custom Snowplow stacks - real-time activation to ads, CRM, and product tools 3. Data warehouse & modeling This is where most setups fail โ€” and where I spend a lot of time. I build: - BigQuery / Snowflake / PostgreSQL warehouses - dbt models for full-funnel metrics (CAC, LTV, retention, payback) - clean, documented metric layers leadership can trust - data quality & observability (schema validation, QA, monitoring) Tools: BigQuery, Snowflake, dbt, SQL, Dagster, Celery 4. Activation, automation & growth ops Data is useless if it just sits in tables. I connect the warehouse and CDP to: - CRMs (Pipedrive) - lifecycle tools (Customerio, Intercom) - ad platforms (Meta CAPI, Google Ads, programmatic) - internal tools via Make / n8n Examples: - automated audience syncs based on real profitability - server-side conversion pipelines that actually improve ROAS - sales-ready enrichment and lead routing 5. Analytics, attribution & decision support I help teams use the data, not just collect it. - Funnel & cohort analysis - Attribution (including MMM when last-click fails) - Dashboards (Looker, Metabase) Training teams to be data-independent Who Iโ€™ve done this for - Fortune 500 companies - Inc. 5000 & YC startups - Publicly traded firms - High-growth SaaS, fintech, e-commerce, AdTech Examples include large Snowplow deployments (150M+ events/month), multi-country CDP rollouts, and full rebuilds of broken analytics stacks that teams had stopped trusting. Why clients hire me - Iโ€™ve been doing this full-time since 2016 - I think in systems, not tools - Iโ€™ve built and operated these stacks myself โ€” not just โ€œconsultedโ€ - Iโ€™m technical, with graduate-level education and business-driven Iโ€™m comfortable explaining complex data systems to non-technical stakeholders If youโ€™re a good fit: Youโ€™ll probably want to talk if: - your analytics data canโ€™t be trusted - GA4 / CDP / ads numbers donโ€™t line up - youโ€™re scaling and your current setup wonโ€™t survive it - you want first-party data ownership instead of black boxes Send a message โ€” Iโ€™m happy to quickly assess your current setup and suggest a clear next step.
