Vikram Kumar worked on backend infrastructure modernization across two repositories, companieshouse/file-validation-api and companieshouse/acsp-api, over a two-month period. He migrated file transfer operations from a Mesos-based system to an ECS-based File Transfer Service, updating configuration properties and API client utilities to ensure seamless cross-service communication using Java and Properties files. In a separate project, he replaced legacy email delivery with a Kafka-backed pipeline, introducing an EmailClient for POST-based sending and integrating with Kafka to improve reliability and scalability. His work focused on API integration, backend development, and configuration management, delivering targeted, end-to-end changes without reported bug fixes.
