## About

Sourabh Pradhan is an IPM (Integrated Programme in Management) student at IIM Bodh Gaya who builds quantitative finance tools for Indian markets, Android utilities, and full-stack web apps. Recurring themes: implementing the math from scratch (Nelson-Siegel-Svensson curve fitting, Itô calculus derivations), pre-computation pipelines that make heavy analytics fast, and shipping on free tiers with zero paid APIs.
