Work Experience
Data Science Intern at Appsoleut Games
Jun 2025 - Aug 2025
Worked on player retention analytics and churn prediction for a driving simulator game.
- Analyzed 10K+ gameplay sessions.
- Built churn prediction models achieving AUC greater than 0.80.
- Segmented players into low, medium and high-risk cohorts.
- Provided retention insights for onboarding optimization.
