Parneet Kaur developed the Metro Card Recharges Integration for the ONDC-Official/automation-config-service repository, focusing on configuration management using YAML. She defined the flow and supported actions for metro card recharges, updating the index.yaml to ensure the configuration accurately reflected the new ONDC:FIS11 domain and version 2.0.0. Her work expanded the top-level use cases, enabling seamless adoption of the new recharge functionality within the automation-config-service. By maintaining traceability through precise versioning and commit management, Parneet ensured that the configuration remained consistent and up to date. The project demonstrated depth in configuration management and domain-driven YAML structuring.
