What I'm looking for

I'm looking to build and deploy production Machine Learning and Generative AI solutions, especially for fintech, fraud detection, risk, and enterprise RAG use cases.

At Easebuzz, I build production Machine Learning and Generative AI solutions for fintech products, including credit card fraud detection and enterprise RAG applications.

I develop scalable pipelines spanning data ingestion, preprocessing, feature engineering, training, evaluation, inference, deployment, and monitoring. My fraud detection platform processes 15,000+ daily transactions and improved ROC-AUC from 0.84 to 0.94, achieving 92% precision and 85% recall.

I also built FinPolicy AI, an internal RAG chatbot that reduced document search time by 70%, improved retrieval relevance by 30%, and reduced hallucinated responses by 40%.
