Data scientist specializing in large-scale credit analytics and ML-driven risk solutions.
IndiaWhat I'm looking for
I am a data scientist with hands-on experience building terabyte-scale credit scorecards, ECL models aligned to IFRS 9, and production ML pipelines using Python, PySpark and SQL. I have driven measurable business impact—improving approvals by 125%, boosting user retention from 10% to 27%, and creating extensive credit-risk feature sets to enhance scorecards.
My background spans end-to-end model development, geospatial clustering for property validation, macro-driven PD forecasting using Vasicek and survival analysis, and deployment of recommender and computer-vision systems. I collaborate across cross-functional teams to translate complex data into scalable production solutions and actionable strategies.
