At TechVision Solutions Pvt. Limited, I sourced and prepared data from databases and APIs, then used SQL and Power BI to turn stakeholder questions into analysis and dashboards.

At Innodata India Pvt. Ltd., I evaluated AI/ML training data, reviewed annotations, and identified errors against client guidelines. I also guided annotators and supported quality across text, image, and video projects.

On my Pizza Sales Analysis project, I used SQL and Power BI to identify sales trends, customer preferences, and peak periods. The analysis reported a 15% improvement in sales forecasting accuracy and a 7% reduction in operational costs.

I also analyzed hotel booking data with Excel and developed a student-performance prediction model in Python. My work includes data cleaning, visualization, and quality evaluation for analytics and AI/ML training data.
