Worked on the juspay/decision-engine repository to implement a configuration-driven mechanism for EMI gateway feature gating, focusing on disabling specific card brands for siOnEmi transactions. Developed a mapping system that associates disabled card brands with particular gateways, integrating this logic into the EMI gateway filtering process. This approach enabled per-gateway control over supported brands, ensuring that unsupported combinations, such as DINERS with CC_AVENUE, are excluded from routing decisions. The work leveraged Rust for backend development and system design, with an emphasis on API development and payment gateway integration, ultimately improving routing accuracy and reducing transaction failures for unsupported card brands.
April 2025 monthly summary for juspay/decision-engine focused on EMI gateway feature gating. Implemented a configuration-driven mechanism to disable specific card brands for siOnEmi transactions, enabling per-gateway control of supported brands and routing decisions. Added a mapping of disabled card brands to gateways and updated EMI gateway filtering logic to exclude unsupported gateways based on the card brand, improving routing accuracy and reducing EMI transaction failures.
