I’m a Data Analyst with 2 years of experience improving analytics workflows and building Power BI–driven insights using SQL and Python. I focus on turning raw data into clear, decision-ready outputs for business teams.

At Tata Consultancy Services, I automated data cleaning and reporting workflows using Quantum, reducing manual effort by 40% and improving reporting frequency. I also analyzed customer segmentation and market trends through Power BI dashboards to help teams identify growth opportunities.

I work closely with stakeholders to understand reporting needs and set up detailed data access control in Power BI so users only see data they’re allowed to access. I’ve also implemented custom Python scripting workflows to process complex datasets, run exploratory data analysis (EDA), and perform root cause analysis to surface trends, anomalies, and actionable insights.

In my end-to-end E-commerce Store Analytics project, I engineered an automated ETL pipeline using Python (Pandas) to clean 7000+ raw records and validated business logic with SQL to ensure 100% data accuracy. I built a Power BI dashboard tracking $233K in revenue using advanced DAX measures, added drill-through for deeper product performance analysis, and translated findings into a technical report and PowerPoint deck that targeted an estimated 10% improvement in subscriber retention.
