Flexiload / Recharge Platform

Developed a robust mobile recharge integration platform using Django and FastAPI to handle automated webhook processing, telecom operator integrations, and real-time transaction management. Implemented webhook endpoints for receiving and processing recharge requests, validating transaction data, handling operator-specific responses, and synchronizing transaction statuses across the system. Designed reliable request-handling workflows for successful, pending, and failed transactions, with appropriate error handling, logging, and response validation. Integrated multiple mobile network operators, including Banglalink, Grameenphone, Airtel, and Robi, while managing operator-specific configurations and API communication. Implemented queue-based processing to support offline transaction handling and synchronization when connectivity is restored. Improved transaction reliability through structured data processing, duplicate-request handling considerations, and consistent status tracking, creating a scalable foundation for automated mobile recharge operations and third-party telecom API integrations.
