Worked on the SwaplyAr-Backend-02 repository, delivering ten features and resolving four bugs over two months. Focused on backend development using TypeScript, NestJS, and SQL, the work included building secure financial account management with role-based access control, robust DTO validation, and comprehensive error handling. Enhanced transaction workflows by modernizing the financial data model, introducing OTP-protected notes, and implementing paginated transaction history retrieval. Improved user verification processes and email notification reliability, while strengthening API security and data integrity. The approach emphasized thorough unit and integration testing with Jest, clear API documentation via Swagger, and privacy-conscious data exposure throughout the system.
