Most businesses don’t have a data problem — they have a reporting and data reliability problem. I help turn messy data and manual workflows into scalable analytics systems that actually drive decisions. With 3+ years of experience and a background in Statistics, I’ve worked with high-volume operational datasets (20M+ rows), building SQL pipelines, KPI frameworks, and Power BI dashboards used by global retail leaders like Walmart, Target, and CVS. 🔹 What I can help you with: • SQL Data Pipelines — ETL, data modeling, performance optimization • Power BI Dashboards — DAX, data modeling, drill-through, RLS • KPI Systems — vendor performance, operations, supply chain analytics • Python Automation — eliminate manual reporting and reduce errors • Data Engineering — Airflow pipelines, AWS (RDS, S3), BigQuery 🔹 Advanced capabilities: • A/B Testing & Experimentation — measure impact of business decisions • Large-scale data processing — optimized pipelines for high-volume datasets 🔹 Proven impact: • Reduced out-of-stock rates by ~18% using analytics-driven insights • Cut reporting time by ~60% through automation • Improved query performance by ~40% via optimized data models I don’t just build dashboards — I build the systems behind them. If your reports are slow, your data is unreliable, or your KPIs don’t make sense — I can help you fix that.
