Enterprise Bulk Card Issuance Workflow

Engineered a bulk provisioning workflow enabling enterprise clients to order thousands of payment cards via a single upload. The system provides locale-specific CSV/Excel templates; upon upload, the Java backend parses the dataset, validates data integrity against business rules, persists records to Oracle SQL, and orchestrates downstream physical card ordering.

• Designed the end-to-end data flow for high-volume batch ingestion, ensuring transactional atomicity
• Integrated OpenTelemetry traces to monitor the parsing and validation stages, ensuring operational safety and quick debugging of client-side data errors
