PROJECT EXPERIENCE
Paywall A/B Test Analysis
https://drive.google.com/file/d/1DMWd87I5Bo85zJlTuS5MjaDlefTVNpTH/view?usp=sharing
Technologies: Python, Pandas, statsmodels, Seaborn.
General description: Analysis of an A/B test evaluating the impact of a "50% discount"
presentation on a subscription paywall.
Idea: To determine if changing the pricing presentation increases the install-to-payment
conversion rate without changing the actual price.
My tasks: Cleaned and processed test data, calculated conversion rates, performed
statistical significance testing (Z-test for proportions), and built visualizations with
confidence intervals.
Result: Proved the statistical significance of the variant group (+45.9% relative CR increase)
and provided actionable business recommendations for the feature rollout.
[E-Commerce Sales Dashboard]
https://lookerstudio.google.com/reporting/3531a956-4103-444d-9d3f-ee0a405eb68b
Technologies: SQL (PostgreSQL), Tableau.
General description: An interactive dashboard for tracking key sales metrics of an online
store.
Idea: Provide a visual tool for the management team to monitor daily sales, identify trends,
and analyze customer purchasing behavior.
My tasks: Extracted and aggregated data using SQL queries (JOINs, Window Functions),
cleaned anomalies, and designed an interactive dashboard in Tableau.
Result: Created a comprehensive dashboard that allows filtering by cohort and product
categories, improving the speed of data-driven business decisions.
