MOHANRAJ S

I’m a Data Analyst with hands-on experience in Nielsen CPG and FMCG analytics, MIS reporting, and KPI dashboard development at NielsenIQ. I’ve engineered Gen AI solutions that saved $80K annually and scaled data processing to 250K+ records/day with 98.5% accuracy, turning syndicated retail data into actionable business insights for 500+ enterprise clients across 90+ countries.

In my current role, I build MIS reports and Power BI dashboards across multiple data sources, track 15+ KPIs for senior stakeholders, and drive faster decision-making by reducing manual quality checks. I also lead data quality root-cause analysis (improving accuracy from 87% to 99.2%), automate ETL and validation pipelines in Python (processing 1M+ records/month at 99.5% accuracy), and apply prompt engineering to improve categorization accuracy—so reporting stays trustworthy, fast, and business-ready.
