Overview

Modern attribution is broken by default. Browser privacy restrictions (Safari ITP, Firefox ETP), content blockers, consent mandates, and fragmented customer journeys across subdomains routinely strip 20% to 40% of conversion data before it reaches your advertising dashboards.

I engineer attribution systems from the ground up as a software discipline—treating every user interaction as a validated telemetry packet rather than a casual marketing tag.

Core Problem Areas Solved

1. Incomplete Purchase & Lead Telemetry

When ad platforms cannot see the conversions your marketing dollars generate, their bidding algorithms bid blindly on unqualified traffic. By moving to dual client-and-server data streams with deterministic event_id deduplication, we restore complete conversion signals.

2. Regulatory Compliance Without Signal Loss

Implementing EU Consent Mode v2 often results in flatlined reporting if executed incorrectly. We configure advanced consent gates that preserve anonymous behavioral modeling in GA4 while strictly honoring user cookie denial.

3. Frontend Speed Degradation

Loading 15 distinct third-party vendor tags directly in the browser ruins Largest Contentful Paint (LCP) and Interaction to Next Paint (INP). By proxying events through a single server-side container, we remove hundreds of kilobytes of third-party JavaScript from the user’s device.
