Worked on the Patthethicc/Biotech_Lab_System repository to deliver a comprehensive enhancement to Purchase Order management, focusing on cross-platform file saving and data model expansion. Leveraged Dart and Flutter to implement file saving for Purchase Order artifacts using the file_saver plugin across Linux, macOS, and Windows. Extended the PurchaseOrder entity to include pack size, quantity, unit cost, total cost, and PO/PI reference fields, and refactored related backend services in Java Spring Boot to remove deprecated fields. Updated CRUD workflows to support the new model, improving data consistency, reducing technical debt, and ensuring reliable operation across multiple platforms.
