Cheezious Platform — Orders & Dispatch Backend
Core backend for a multi-outlet food ordering platform, covering orders, payments, refunds, and rider dispatch.
Overview
A backend engagement delivered as part of the Techbang team for the Cheezious food ordering platform, supporting order lifecycle management, payment and refund processing, and real-time dispatch coordination between outlets and delivery riders.
The Business Problem
The platform's serverless architecture was becoming costly to run and difficult to extend as order volume and integration complexity grew, while dispatch and payment workflows needed more resilient failure handling in production.
The Solution
Migrated core services from a serverless setup to a microservices architecture, integrated multiple local payment gateways directly into the order and refund flows, and hardened the dispatch pipeline with better validation, logging, and failover handling around cloud storage operations.
Our Contribution
Engineered the backend systems supporting orders, payments, refunds, and rider-assignment workflows, led the serverless-to-microservices migration, and resolved critical production issues in dispatch and file-storage handling.
Key Functionality
- Order lifecycle and refund management APIs
- Rider-assignment and dispatch coordination workflows
- Secure integration with HBL Pay, Bank Alfalah, and XPay
- Failover and validation logic for cloud storage operations
