  • Co-led the creation of an advanced Rule Engine, a decision tree-based system that streamlined the fraud rule lifecycle — reducing the time to implement new rules from several days to just a few hours. Initially built for the credit card product, it was later adopted across UPI and Borrow platforms after achieving significant success.
  • Built an internal Fraud Operations Portal to enable risk teams to view and act on flagged transactions, greatly improving fraud triage and operational workflows.
  • Implemented foundational fraud checks across all card transactions and extracted fraud logic from a monolith into a standalone microservice, which improved system scalability and clarity. These efforts led to a 90% reduction in fraud within two months, laying the groundwork for the Rule Engine.
