About Souvik Das
Data Scientist with 4 years of experience in banking analytics at HDFC Bank, specialising in propensity modelling, customer segmentation, and cross-sell optimisation across liabilities portfolios — CASA, FD/RD, Merchant & Payments services, UPI, Salary, and HNW portfolios.I build production-grade machine learning solutions that go live, stay live, and drive measurable business impact. My work spans the full analytics lifecycle — from raw data exploration on large-scale Databricks lakehouses to deployed models and stakeholder-facing dashboards in Power BI. I work with large volumes of structured and unstructured banking data, applying models ranging from Logistic Regression and Gradient Boosting to LightGBM, XGBoost, and clustering-based recommendation systems.Beyond core modelling, I collaborate closely with business, operations, and social banking teams to translate data into decisions — whether that\'s sharpening campaign targeting, building portfolio monitoring tools, or strengthening governance in financial inclusion programs. I take ownership of problems end-to-end, from understanding the business question to deploying a solution that teams actually use.My technical toolkit includes Python, SQL (Trino/Postgres), PySpark, Power BI, and Databricks — with a strong focus on building scalable, production-ready solutions in lakehouse environments.
