BRIDGING DATA ENGINEERING & BUSINESS STRATEGY

I am a Data & Technology professional with a Master's in Computer Science (CGPA 8.4) and nearly 2 years of enterprise experience across heavy manufacturing (Innomotics India Ltd.) and multi-channel e-commerce (Sounce Retail).

I do more than create static reports — I work across the complete data lifecycle: extracting and engineering data from complex sources, building Star Schema models, automating manual operational bottlenecks with Python and VBA, and delivering decision-ready Power BI dashboards, full-stack software applications, and AI-assisted workflows.
