Experience

Data Scientist

AB InBev: Anheuser-Busch InBev, Bengaluru
Aug 2022 - Present · 3 years 11 months

Leading development of Cash.AI, a GenAI-powered document intelligence platform using LLMs to automate remittance and claims extraction across heterogeneous customer formats (Excel, PDF, scanned images).
Designed a scalable, country-agnostic processing pipeline, reducing remittance processing time to ~5 minutes per batch and enabling near real-time finance operations.
Deployed the product across seven countries, achieving enhanced data accuracy, ~70% increase in analyst efficiency, and an 82% overall touchless processing rate, driving measurable improvements in OTC performance KPIs.
Ensured production-grade security and governance by remediating vulnerabilities via Snyk, SonarCloud, and Apiiro, and completing MICS (Minimum Internal Control Systems) compliance for GenAI deployment in a regulated environment.
Developed a weekly price direction prediction model using ensemble techniques (Random Forest, XGBoost), achieving 77% F1-score and delivering $1.2M in cost savings.
Implemented Optuna-based hyperparameter optimization to improve robustness and generalization.
Built a 12-week price forecasting model using Orbit DLT, achieving 76% directional accuracy and generating $2.3M in savings for procurement hedging decisions.
Created an ensemble model for hedging instrument selection (forwards/options), achieving an F1 score of 88% and delivering $1.6M in savings.
