Key areas of focus and impact include: \* Data Quality & Governance: Maintained 97%\+ QA\-verified accuracy across 1\.5M\+ records, ensuring data integrity and reliability for critical business functions\. \* Process Optimization: Co\-built an annotation process from pilot to launch at Amazon, achieving 98% accuracy across 1,600\+ daily records\. This involved authoring SOP updates, identifying edge cases, and training team members, leading to significant operational efficiencies\. \* Business Intelligence & Reporting: Architected and deployed interactive Power BI and Tableau dashboards, visualizing datasets up to 200K\+ rows to uncover performance gaps and inform strategic recommendations\. \* Advanced Analytics: Executed an MBA capstone project utilizing regression, ANOVA, and chi\-square analysis to derive deep insights into consumer behavior\. \* SQL & Python Proficiency: Applied SQL for complex data querying and analysis, alongside Python \(Pandas, NumPy\) for extensive exploratory data analysis and visualization\. \* Operational Efficiency: Identified 200\+ pricing and ERP data discrepancies, streamlining the correction process by 73% \(from 30 to 8 minutes\) at MDL Vishal India, significantly reducing operational overhead\. \* Cost Reduction: Negotiated vendor pricing and optimized purchasing, cutting monthly procurement spend by over 10% on a ₹25 lakh average monthly spend, while managing hundreds of purchase orders\. I am passionate about transforming complex data challenges into clear, actionable solutions that drive measurable business outcomes\. Currently seeking Data Analyst and Business Analyst roles where I can apply my skills to further enhance process efficiency, data quality, and strategic decision\-making\.
