What I'm looking for

I seek roles where I can lead analytics and BI initiatives, build scalable data pipelines and models, and collaborate cross-functionally to drive measurable operational and product impact.

I am a senior data analyst and BI professional with extensive experience translating complex data into actionable insights for retail, supply chain, and operations.

I have led end-to-end analytics initiatives, designing SQL-driven data pipelines, building automated dashboards, and deploying predictive models (RandomForest, XGBoost, SVM) to improve procurement, inventory, and product performance.

My work has delivered measurable impacts including an 80% reduction in partial deliveries for key accounts, a 90% improvement in customer satisfaction metrics, and improved inventory planning through a BI-driven inventory intelligence system.

I combine strong technical skills (Python, SQL, PySpark, PowerBI/Metabase), data modeling, and cross-functional collaboration to deliver reliable, scalable analytics and clear, actionable reporting that supports executive decision-making.
