Challenge:A 54% discrepancy between GA4 ($31K) and actual revenue ($52K via Stripe + RevenueCat). Missing purchase events across subscription and credit plan flows meant the marketing team was optimizing against incomplete data.

Solution:Audited the full GTM container, implemented a Stripe-to-dataLayer fix distinguishing purchase types, built new conversion tags for Meta, Google Ads, and TikTok with full QA, then extended with server-side Meta CAPI.

Challenge:After fixing the revenue tracking gap, the client needed server-side tracking to recover conversion signals lost to ad blockers and iOS privacy restrictions.

Solution:Built full server-side Meta CAPI implementation with Cloud Run infrastructure, Stripe webhook integration, client/server event deduplication, and first-party GTM hosting on a custom subdomain.

Challenge:GTM was installed but zero dataLayer values were being passed — GA4 received no useful event data. Marketing had no visibility into the user journey from signup through purchase.

Solution:Wrote a complete 5-event dataLayer specification covering the full user journey, with dynamic vs. static field mapping and developer handoff documentation.

Challenge:Pinterest lead conversion events were consistently attributing to the wrong ad account. The agency team couldn't identify why conversions were being misattributed despite a correctly configured GTM pixel.

Solution:Identified root cause as a legacy Pinterest pixel loaded via Adobe Launch conflicting with the GTM pixel. Produced a full investigation report with call stack analysis and Loom walkthrough for the agency team.

Challenge:Pre-migration compliance review needed for a luxury brand preparing to launch a new booking engine. Existing pixel setup had unclear data processing agreements and consent gaps.

Solution:Conducted a comprehensive compliance audit covering GDPR data transfer obligations, Meta and Google Ads DPAs, dataset category configuration, third-party integrations, and cookie consent requirements.

Challenge:A hospitality agency wanted to activate Google Hotel Ads for multiple clients but lacked clarity on technical requirements, connectivity partners, and per-property readiness.

Solution:Delivered a full technical assessment covering Hotel Center access pathways, connectivity partner requirements, agency capability scope, and per-property readiness evaluation with clear next steps.

Challenge:An Australian e-commerce marketplace needed a data collection strategy and full GA4 event tracking setup built from scratch to understand user behavior across their platform.

Solution:Designed the complete data collection strategy and implemented full GA4 event tracking through GTM, covering the marketplace's unique buyer and seller journeys.

Challenge:A Nordic e-commerce agency serving marketplace sellers needed a scalable data pipeline handling multiple stores, multi-currency normalization, and tenant isolation — at minimal cost.

Solution:Built a production-grade multi-store Shopify pipeline on GCP with incremental loads, retry logic, tenant isolation, and multi-currency normalization. Runs on Cloud Run with Cloud Scheduler.

Challenge:An agency managing Google Ads and Meta Ads for field service businesses using Jobber had no way to connect ad spend to actual job revenue. Reporting was manual and couldn't attribute which channel drove real bookings.

Solution:Built a unified data pipeline pulling Google Ads, Meta Ads, and Jobber CRM data into BigQuery. Created cross-channel attribution models linking ad clicks to booked jobs and completed revenue.

Challenge:An e-commerce business had GA4 data in BigQuery and CRM data in a separate system with no linkage. They couldn't connect website behavior to actual customer records, making LTV analysis and personalization impossible.

Solution:Built a full data warehouse linking GA4 BigQuery export with CRM data at the user level using dbt for transformations, Cloud Run for orchestration, and Cloud Scheduler for automated runs.

Challenge:Multiple Shopify brands across coaching, health, and retail verticals needed proper conversion tracking — from GTM setup through GA4 e-commerce events and server-side implementations.

Solution:Delivered end-to-end tracking implementations across multiple brands including GTM container setup, GA4 e-commerce events, Meta Pixel, Google Ads conversions, and server-side GTM.
