Built a Warehouse Management System using Java 21 and Spring Boot 3 with modules for Purchase Orders, GRN, Parts, Vendors, and Documents — following Controller → Service → Repository layered architecture. Designed and implemented State Flow Transitions for Purchase Orders (OPEN → PICKING → ORDERED → INVOICED → RECEIVED), enforcing transitions through controller/service logic and JPQL @Modifying repository queries. Modeled domain entities using JPA/Hibernate with OneToMany/ManyToOne relationships (PurchaseOrder–PurchaseDtl, GRN–GrnDtl) and foreign key constraints across PostgreSQL schemas. Implemented GRN workflow: auto-generated GrnDtl from INVOICED PO line items, computed line totals, and managed per-line ACCEPT/REJECT status updates via custom JPQL queries. Delivered reporting and export features — Excel reports (Apache POI), PDF invoice generation (iText), and dashboard charts (JFreeChart) — alongside multipart file upload/download with BLOB storage in PostgreSQL. Exposed REST endpoints for master data (UOM) to support AJAX integration, and built server-side rendered UI using Thymeleaf + Bootstrap with status-based action visibility (Confirm / Invoice / Print / Receive).
