Modular ERP Frontend


A highly scalable enterprise resource planning (ERP) system designed to manage administrative, logistical, and human resource operations. Built on a modular architecture, the system can coordinate vital business segments, including human resources, and event coordination.

Key functionalities include a multi-party digital signature workflow for secure document dispatch approvals, dynamic PDF previewing, and spreadsheet data export (.xlsx) directly from table filters. The platform is backed by a robust client-side permission framework that validates user privileges for every view, ensuring strict access control. The UI features highly interactive DataTables, smooth responsiveness, and clean state workflows.

Dual-Currency Receipting System (SIRE 2T)

Custom dual-currency retail application with real-time inventory and offline-first local data persistence.

React JavaScript

Dual-Currency Receipting System (SIRE 2T)


This receipt system for small businesses was designed for simplicity and intuitiveness, allowing any employee without management system knowledge to use it easily. Developed in a local environment, it can also run on two or more computers simultaneously, integrating inventory and shipping into a single system, all from a main computer. This eliminates the need for a stable 24/7 internet connection and reduces loading and waiting times.

Furthermore, this system features an automated user management section that is fully autonomous from the main or administrator computer, feeding data to the rest of the system. Completely customizable and adaptable to your business or venture, we can implement it at a two-currency rate or according to your specific requirements. A key benefit of this system is the ability to review your transactions at the end of the day, resulting in a printed receipt with a detailed description.
