PROFILE
Shankar Singh C
Shankar Singh contributed to the juspay/decision-engine repository, focusing on backend enhancements for card-processing flows over a two-month period. He developed features to improve co-badged card data modeling and debit routing, expanding the schema to support nullable fields and refining response generation. Using Rust and SQL, Shankar introduced granular network-level saving calculations, robust error handling, and configuration management for network fees, particularly addressing Mastercard pricing alignment. His work included comprehensive API documentation and code refactoring, which improved maintainability, testability, and developer onboarding. These changes increased routing accuracy, data reliability, and operational consistency across development, staging, and production environments.
