AC SEC Enterprise Management System

Challenge

AC SEC needed more than a public-facing website. The business required a secure internal platform for managing employee records, company assignments, departments, roles, working-hour entries, payments, account statements, reports, exports, and administrative permissions. The system also had to preserve financial accuracy over time, so historical working-hour records could remain stable even when employee salaries, company extra amounts, or master data changed later.

Solution

CloudGoUp designed and developed the full platform end to end using Next.js, React, TypeScript, Tailwind CSS, Recharts, Lucide icons, NestJS, Prisma ORM, MariaDB/MySQL, JWT authentication, rotating refresh-token cookies, Argon2id password hashing, role-based permissions, CSRF header protection, secure cookies, rate limits, audit logs, strict DTO validation, and export workflows for CSV, XLSX, PDF, and print-ready statements. The implementation covered system architecture, database schema, backend API, frontend enterprise UI, authentication and authorization, working-hours and payment logic, reporting, dashboard analytics, deployment preparation, security hardening, and operational documentation.

Outcomes

• Delivered a secure internal enterprise workspace tailored around AC SEC's real operations
• Centralized employees, companies, departments, roles, working hours, payments, account statements, reports, exports, and permissions
• Implemented historical salary snapshots so working-hour financial records preserve salary, company extra amount, hourly rate, and calculated amount at the time of entry
• Created dashboard analytics, filtered reports, CSV/XLSX/PDF exports, and print-ready account statements
• Prepared production deployment with Plesk Node.js, a single app.js entrypoint, environment validation, Prisma migrations, and backup/restore scripts
