I’m a Senior BI Developer specializing in Marketing Mix Modeling (MMM) data engineering across the complete marketing funnel. I integrate diverse data sources—from digital platforms like CM360, DV360, YouTube, and Google Ads to offline channels and client data such as GA4, competitor intelligence, brand metrics, consideration, and sales.

I’ve delivered insights for 10+ enterprise clients, including Fortune 500 companies, government agencies, and leading Australian brands. In my current role, I led MMM data engineering for clients like Mercedes Benz, Telstra, AMEX, VicRoads, Bunnings, TafeNSW, Virgin Australia, Suncorp, and Celebrity Cruises.

I engineer large-scale data harmonization, cleaning, and standardization using AI/ML technologies—reducing data quality issues by 70% through cross-channel harmonization across 15+ sources. I also implemented AI-driven data harmonization using Claude to optimize ETL transformation rules for complex schema mapping across diverse client systems.

I build and operationalize end-to-end BI solutions, including 15+ enterprise dashboards for 60+ stakeholders, reducing BI dependency by 40%. With Matillion ETL pipelines processing 500M+ records daily from 15+ sources and MMM-optimized data models enabling 50+ Data Scientists, I focus on reliable pipelines, clear KPI definitions, and actionable executive reporting.
