Pargas Sanat Viona Platform
Pargas Sanat Viona is a full-stack wholesale auto-parts platform I built for the Pargas Sanat Viona industrial and sales group, designing its architecture, database, API and user interface end to end. It serves 50 dealers and a catalogue of more than 400 products.
The backend is split into users, product catalogue, orders, statistics and reports, chat, support and notifications. It is written with Django and Django Ninja, authenticates with JWT access/refresh tokens, runs real-time dealer–support chat over WebSockets (Django Channels), and handles background and scheduled work such as SMS and statistics with Celery on Redis. Pro-forma invoices are generated as Persian PDFs and reports export to Excel.
The front end is a React, TypeScript and Vite SPA with an RTL Mantine UI, TanStack Query for server data, TanStack Table for the product grid, ECharts for dashboard charts and Jalali dates throughout.
Data lives in PostgreSQL, with Redis for caching, chat messaging and the task queue. It is deployed on Ubuntu behind Nginx, with Gunicorn for the API, Daphne for WebSockets and systemd. The platform took two months to build and I continue to support and extend it.
