Backend platform for food, grocery, medicine, vendor operations, rider delivery, real-time support chat, restaurant menu sync, reels, tax invoicing, and admin analytics.
Quikle is a multi-service delivery backend platform designed to manage food, grocery, and medicine ordering workflows from one scalable system. The platform supports customer ordering, vendor management, rider operations, restaurant menu synchronization, Petpooja integration, real-time support rooms, promotional reels, GST-ready invoice calculations, admin dashboards, and operational monitoring.
A backend-first summary of the product problem and the solution direction behind the full project delivery.
Quikle is a multi-service delivery backend platform designed to manage food, grocery, and medicine ordering workflows from one scalable system. The platform supports customer ordering, vendor management, rider operations, restaurant menu synchronization, Petpooja integration, real-time support rooms, promotional reels, GST-ready invoice calculations, admin dashboards, and operational monitoring.
The client needed a centralized backend system that could support multiple delivery verticals such as food, grocery, and medicine while managing vendors, riders, customers, orders, restaurant menus, stock, taxes, support communication, and admin operations. The system also required external restaurant API integration, real-time chat support, medicine-order verification flows, and dashboard-ready reporting without becoming fragile as business operations scaled.
I developed a modular FastAPI backend using Tortoise ORM, Redis, JWT authentication, role-based access control, WebSocket communication, and structured service layers. The backend includes modules for authentication, vendor and rider workflows, product and category management, restaurant menu sync, Petpooja integration, order processing, medicine verification, GST-inclusive invoice calculations, support chat rooms, reels, notifications, dashboard summaries, and deployment-ready infrastructure using Docker, Nginx, VPS hosting, and GitHub Actions CI/CD.
A single system architecture snapshot preserved as proof of the delivery design and implementation flow.
The stack used across the full build, covering service logic, data storage, infrastructure, cloud setup, frontend integration points, and delivery tooling.
The core capabilities were implemented as production-facing modules, shaped for real usage, maintainability, and future scale.
