Problem
The client tracked beverage stock by hand and needed one system for it. The tricky part was modeling the dependencies between live stock levels, expiration dates, and automated reordering, while enforcing strict per-role permissions.

- Methodology
A team project building an order management system that automates procurement and stock logistics. Within the Spring Boot monolith, I designed the relational database schemas, the inventory depletion models, and the role-based access controls.
Approach
We built a monolithic Spring Boot application as the central hub. I owned the inventory module: the business logic that flags low-stock items and dispatches procurement orders automatically. The frontend is server-side rendered with Thymeleaf.
Outcome
Delivered a working prototype that digitized the manual workflow, hitting every sprint deliverable on schedule across the full Scrum cycle.
Architecture
A classic Spring Boot Model-View-Controller structure, with Spring Data JPA for object-relational mapping and Spring Security for granular access control separating the warehouse roles.
Highlights
Stock Tracking
Live monitoring of beverage stock levels with automated low-stock alerts.
Procurement Automation
Supplier orders are generated automatically when inventory dips below defined thresholds.
Role-Based Access
Authentication that separates administrative duties from standard staff operations.
Financial Logging
Accounting features tracking procurement costs against internal usage and sales.
Timeline
Requirements
Analyzed the existing workflow and mapped the logistics processes to model.
Backend
Built the relational models, depletion engine, and ordering system.
UI and Testing
Integrated the server-rendered Thymeleaf views and completed the JUnit suites.
Delivery
Handed over the prototype with all acceptance criteria verified.
