Overview

Client: Rayon Energy, Khartoum · Role: Sole developer, AI-assisted · Period: Apr – Jul 2026 · Status: Completed; not deployed by the client

Sales, products and inventory, quick fee buttons, partner profit tracking and profit sharing, supplier and customer accounting, export to CSV, Excel and PDF, and dashboards, all in an Arabic interface. Built in ten spec-driven phases (71 commits).

Architecture

Money is calculated with exact decimal arithmetic instead of floating point, so prices, fees and VAT never drift by a fraction. The desktop version packages the backend and frontend into one Windows installer.

Outcomes

Completed through ten feature phases, from core POS to supplier and customer accounting, with a Windows desktop installer.
