Digitizing Gate Access for
Visakhapatnam Steel Plant
How I engineered a role-based Gate Pass Management System to secure entry for thousands of employees and reduce manual verification time by 50%.
🛑 The Challenge
Processing gate passes for contractors and employees at RINL was a manual, paper-heavy process. Security personnel had to manually verify physical IDs against printed lists, leading to:
- Long queues during shift changes (20+ minutes).
- High risk of unauthorized entry due to human error.
- No digital audit trail for visitor tracking.
💡 The Engineering Solution
I developed a Centralized Digital Gate Pass System using Java Spring Boot. The system replaced paper logs with a role-based digital workflow, allowing authorized requestors to generate passes and security to verify them instantly.
Secure RBAC
Implemented strict Role-Based Access Control. Only Department Heads could approve passes, while Security could only 'View & Verify'.
Oracle Optimization
Designed normalized database schemas to handle 1000s of daily transaction logs without latency.
