Experience

1. Lead Data Scientist

   Zupee

   Apr 2024 — Present · Gurugram, IN

   Leading applied ML and AI initiatives across gaming and new media verticals, enabling data-driven product decisions and measurable business growth. Developed a multimodal generative AI system to create promotional videos for micro-drama content, reducing promo production time from weeks to minutes. Strengthened user acquisition funnel performance through fast and varied experimentation. Built a RAG-based conversational chatbot combining multilingual semantic embeddings, vector search retrieval, and LLMs with streaming responses, to improve content discovery and engagement. Designed a proactive loss-management framework leveraging behavioural and financial signals to identify at-risk users, enabling targeted interventions that improved retention and lifetime value. Built churn prediction models and data-driven intervention strategies (personalisation, incentives, engagement nudges) to reduce user drop-off and optimise lifecycle outcomes. Modelled user tenure and lifecycle trajectories to forecast retention dynamics and applied inference techniques to uncover key churn drivers and optimise intervention timing. Developed fraud detection models integrating behavioural and graph-based network signals to uncover collusion patterns, producing precise and actionable outcomes.
