STOP. Do not hire a "Digital Marketer" to fix your data infrastructure. If you are reading this, you likely have "Dirty Data." Your ROAS doesn't match your bank account, your GTM is a mess of broken triggers, and you suspect you are bleeding budget on "Zombie Campaigns." I am a Technical Marketing Science Partner specializing in Forensic Data Audits. I don't "guess" at your tracking problems. I use proprietary Python automation and Google Ads Scripts to audit your account with a level of depth that manual analysis cannot match. Who I Help: I partner specifically with Boutique Performance Agencies and High-Volume Advertisers who need to trust their numbers again. My "Revenue-Tracking Recovery" Scope: I offer a specialized, fixed-price forensic sprint to clean your data ecosystem: Forensic Auditing: I extract data via API to find discrepancies between Ad Spend and backend Revenue (identifying wasted spend). Server-Side Tracking (GTM/GA4): Implementing robust tracking (CAPI) that survives iOS14+ and ad blockers. Automated Anomaly Detection: Scripts that alert you when tracking breaks (so you don't find out 30 days later). The "Truth" Dashboard: Building Looker Studio reports that reflect actual profit, stripped of vanity metrics. Why Me? The Trifecta: Financial Rigor: Former Citibank. I treat your data like a bank balance. Zero-error tolerance. Engineering: I code in Python to automate complex data tasks. Strategy: Former Publicis. I understand the Media Buying pressure you are under. Technical Stack: Platforms: Google Ads, GA4, Google Tag Manager (Web & Server), Facebook CAPI. Engineering: Python (Pandas/NumPy), Google Apps Script, BigQuery, Looker Studio. Engagement Model: I work on a Fixed-Price Basis (The Recovery Sprint). I am not looking for hourly "maintenance" work. I come in, I fix the engine, I verify the data, and I hand you the keys. If you want a "Yes Man" to install a plugin, hire a junior. If you want a Forensic Auditor to protect your P&L, invite me to the job.
