Telecom Services & Hawala Platform
Havale Online – Online Telecom Hawala Management & Purchase System
Development of a specialized multi-module platform for online buying, selling, and management of telecom hawala. The frontend is built with Vue 3 (Composition API) and centralized State Management, delivering a fast, lag-free SPA experience for financial transactions. The backend, powered by Django (Django REST Framework), provides a robust, secure API‑first architecture handling financial transaction processing, hawala inventory management, multi-factor authentication, and integration with third-party telecom APIs. The project also includes a TWA app that wraps the web version into a native-like Android experience.
