@pujalanagavardhan
Business Analyst turning SQL, Python, and Power BI into actionable business insights.
IndiaWhat I'm looking for
I’m a results-driven Business Analyst with expertise in SQL, Python, Power BI, Excel, and PostgreSQL. I transform complex datasets into actionable insights, KPI reporting, and business recommendations through strong data cleaning, EDA, and dashboard development.
In my SaaS customer retention and revenue analytics project, I built a PostgreSQL customer 360 model and delivered an executive Power BI dashboard to monitor real-time revenue health and at-risk segments. I also analyzed telecom churn patterns and produced diagnostic visualizations for non-technical stakeholders, using hypothesis testing to validate retention drivers (p < 0.05) and translate findings into clear engagement levers.
Experience
Work history, roles, and key accomplishments
Built a SaaS customer retention and revenue analytics model by integrating 5 data sources for 5,000 customers into a PostgreSQL customer-360. Quantified ₹136M ARR and ₹11.3M MRR, identified onboarding drop-off and low adoption as key churn drivers, and delivered an executive Power BI dashboard with churn heatmaps and cohort views.
Analyzed telecom churn patterns across 3,000 customers and identified 38% of churned users as month-to-month with under-3-month tenure. Engineered 6 derived churn features, created diagnostic visualizations for stakeholders, and surfaced a high-value retention cohort estimated at ~18% of the customer base.
