Islamova12345
Gulshan Islamova developed core modules for the Digital-Invoice-Processing-System repository, focusing on invoice operations tracking, item management, and measurement units management. She applied Java and Spring Boot to design RESTful APIs, leveraging DTO patterns, MapStruct, and Lombok for consistent data modeling and maintainable code. Her work included implementing Liquibase-based database migrations, JWT-secured multi-channel authentication with Telegram integration, and Excel export features for financial reporting. By standardizing DTO naming and refactoring service layers, Gulshan improved data integrity and API reliability. Her engineering approach emphasized robust schema management, transactional safety, and test-driven development, resulting in scalable, audit-ready backend services.

Aug 1, 2025In August 2025, delivered key capabilities for cybernet-internship-2025/Digital-Invoice-Processing-System across item management, measurement API, and invoice export features. Implemented Item Management Enhancements and In-Invoice Item Handling with new endpoints (retrieve by ID, delete by item or in bulk, delete all for an invoice), multi-item add support, and ItemStatus enum; refactored ItemService to avoid redundant DB calls and fixed insert issues for data integrity. Advanced the Measurement Service API with a rename from getByNameResponse to findByName for clarity, added unit tests, included ID fields in responses, and aligned endpoint paths; fixed a measurement service bug to ensure reliable data retrieval. Enabled Invoice Export Features to produce Excel exports for Received and recipient invoices with flexible filtering, dedicated request objects, and consistent API design including header constants. Addressed critical bugs (insert problem in items table; measurement service bug) to strengthen reliability and reporting accuracy. Overall, these efforts improve business throughput, enable richer financial reporting, and demonstrate robust API design, test-driven development, and performance-oriented refactoring.
