About the Project
We are building a Warehouse Management System (WMS) to support 24x7 warehouse operations, configuration, and monitoring.

- Ensure real-time synchronization across handheld devices and dashboards.
- Optimize PostgreSQL queries for large, high-volume datasets.
- Integrate with barcode/QR/RFID logic and external systems if needed.
- Contribute to system monitoring (Prometheus/Grafana, Spring Actuator) and testing (JUnit, Mockito, K6).
- Collaborate with web (Laravel/Next.js) and mobile (Flutter) developers to align API contracts.
- Participate in Agile ceremonies (backlog grooming, sprint demo, retrospective).
