SYSTEM 01 · ADS ATTRIBUTION & TRACKING

Every dollar of ad spend, traced to real revenue.

Google, Meta or TikTok: I find where your tracking leaks, wire server-side conversions to closed deals instead of form fills, and leave you a dashboard that says what to scale and what to kill.

01 · GOOGLE ADS · LUXURY REAL ESTATE

Bidding on closed commissions, not clicks.

A 189-ad-group account across 9 city silos was optimizing on form fills, and its conversion data was corrupted by a SHA256 double-hashing conflict. I diagnosed the conflict deep in the GTM code within hours, then bridged real transaction data into Google Ads: a custom Zapier “Radar” system, offline conversion imports, GCLID integrity checks, silo leak audits and Looker Studio telemetry.

“If you need a Master Engineer who can weaponize your data, Tim is the only choice. 5 stars is an understatement.”

The live account: $1.7M in managed spend across the 9 city silos. Campaign names and budgets anonymized.

02 · META + TIKTOK CAC · EDUCATION

Every enrolled student, traced to its ad.

A tutoring academy’s leads moved to WhatsApp and Telegram, where ad platforms lose the trail; enrolment happened weeks later in chat. Click IDs and source data are captured before the handoff, stored in Peppercloud CRM custom fields, and fired back to Meta and TikTok the moment a lead reaches Enrolled, with a blended CAC dashboard that counts referral payouts in the spend.

03 · REVENUE DATA PLATFORM · BENCH ACCOUNTING

The pipelines behind $89M of revenue analytics.

At North America’s largest small-business bookkeeper, I built the AWS ETL and dbt + Snowflake models feeding marketing attribution, churn forecasting and revenue reporting for 11,000+ clients: tested, documented and trusted downstream.
