I've built end-to-end analytics projects across retail sales, HR attrition, e-commerce behavior, and inventory optimization, translating large datasets into clear recommendations. My retail dashboard covered 50,000+ transactions and cut manual reporting time by approximately 30%.

Using Python, I found that the top 10% of e-commerce customers drove 40% of revenue across 500,000+ transactions, while SQL analysis showed the top 20% of customers generated 60% of total revenue. I also built an inventory pipeline across SQL, Python, and Power BI that recommended actions projected to reduce overstock costs by 15%.

At Tata Advanced Systems Limited, I supported production traceability, inspection-data verification, non-conformance reporting, and root-cause analysis under AS9100D guidelines. I bring an aerospace engineering foundation, GATE qualification, and Google Data Analytics certification to practical business analysis.
