• Data Integration & Automation: Connect warehouse data sources and automate data movement using SQL, Python, and API integrations to replace manual spreadsheets.

• Security & Reliability: Implement user authentication, role-based access control (RBAC), data validation, logging, and performance optimization.

• Cross-Functional Collaboration: Partner with Frontend Developers, Project Managers, and Warehouse Operational Leaders to deliver features end-to-end.

Key Deliverables by the End of Your Internship

1. Fully Functional Platform Backend: A ready-to-use backend layer supporting workforce planning, dashboards, and live KPI monitoring.

• API Integration: Connect user interfaces with backend REST APIs, gracefully handling state management, loading indicators, and error validations.

• User-Centred Testing: Observe actual warehouse operations, gather feedback from operational users, and refine interfaces to make them effortless for teammates to use.

• Code Quality: Maintain clean, structured, and well-documented frontend code using modern Web development practices.

Key Deliverables by the End of Your Internship

1. Live User Interface: A fully integrated, responsive web platform delivering intuitive dashboards and operational workflows for warehouse leaders.
