What I'm looking for

I’m looking for a Senior Data Scientist role where I can ship production ML/LLM systems, blend research with execution, and drive measurable growth in revenue, engagement, and operational efficiency through data-driven automation.

I’m a Senior Data Scientist and AI Researcher with 6+ years bridging academic innovation and real-world industry applications. I focus on machine learning, deep learning, and reinforcement learning to turn data into automated, scalable outcomes.

In industry roles, I’ve built production-ready ML systems—from Customer 360 governed records for ~1M customers to churn and reactivation frameworks with scoring-to-CRM activation. I also develop leakage-safe pipelines with quality gates so exports only happen when results pass.

My work has translated into clear business results: I improved insurance underwriting loss ratio by 18% and increased renewal rates from 68% to 85%. I’ve also used segmentation and A/B testing to raise conversion rates by 15% and identify high-value behavioral clusters for targeted marketing.

I enjoy pairing strong NLP and LLM experimentation with practical deployment. From reducing manual sentiment-analysis effort by 60% to improving student engagement by 40% and learning outcomes by 35%, I aim to build AI systems that scale while staying accurate, reliable, and measurable.
