securityERP - Security Company Management System

A full-stack ERP system for security companies, covering guard attendance, employee records, location/contract management, and role-based admin control. Includes a NestJS + PostgreSQL backend secured with JWT auth guards, a Next.js admin dashboard, and a companion Expo mobile app for guards to check in/out and for admins to manage employees and locations on the go. Built independently while working at a security company, with a focus on production-grade security (IDOR fixes, hashed credentials, protected routes) and real-world operational needs.
