IndiaWhat I'm looking for
At Omnicom Global Solutions (Annalect India), I architect and deploy Microsoft Fabric OneLake Medallion Lakehouses that turn billions of ad-tech data points into real-time executive decision cockpits.
I've engineered automated Python and PySpark pipelines that replaced manual workflows and cut monthly processing cycles by 30%. I also led a zero-downtime migration from legacy reporting infrastructure to OneLake.
Previously at NKT India, I built automated Python pipelines and market-mix models that eliminated 40% of manual data handling, while creating data-backed expansion roadmaps that improved marketing efficiency by 15%.
Across consulting, media, and AdTech work, I've used SQL and Power BI to build predictive models and executive dashboards, improve conversion rates, and unlock new revenue. I bring data modeling, governance, and delivery together for reliable business outcomes.
