Hey there, I'm Ojas! ๐Ÿ‘‹

Data Scientist & ML Engineer specializing in large-scale ML pipelines, RAG/LLM applications, and risk analytics on multi-terabyte datasets.
PySpark | Responsible Gambling Modelling | Risk Modelling | RAG/LLMs|

Currently leading risk modeling at Rutgers Center of Gambling Studies, where I work on 4.5 TB / 13.6B+ record datasets to detect high-risk gambling behavior using clustering (KMeans, GMM), gradient boosting (LightGBM), and anomaly detection pipelines.

I also design RAG-powered AI applications for real-time analytics and financial decision-making, delivering systems that scale from prototype to production and directly inform policy and business strategy.

Open to connect for exciting opportunities! ๐Ÿš€
