Shrey Madan

I’m a data & analytics professional with 5+ years of experience building ETL pipelines (Funnel → BigQuery → Tableau) for multi-channel marketing data. In my current role, I built and automated an end-to-end Funnel.io pipeline across 5 channels and 4 ad platforms, reducing weekly reporting turnaround by 30%.

I focus on data validation, reconciliation, and making dashboards audit-ready. I standardized taxonomy and transformation rules to catch anomalies at the source, cutting data-quality issues flagged by stakeholders by 25%, and I automated multi-source SQL reconciliation to save 5+ hours/week while enabling daily dashboard refreshes. I also designed and shipped 10+ executive and team Tableau dashboards, and I partner on incremental-lift studies (causal impact, geo-lift) to turn findings into spend-reallocation recommendations.

Previously, as a Market Research Analyst, I created interactive Tableau dashboards after cleaning and preparing data with SQL and Excel, tracked visitor flow with Google Analytics, and aligned insights with client and business objectives. Before that, at Infosys (Amex Process), I used advanced Python for data cleaning and led automation to reconcile data across sources, reducing manual effort by 20%—reinforcing my bias for accuracy, repeatability, and stakeholder-ready storytelling.
