A comprehensive, production-grade clone of Delivery Hero / Foodpanda built with modern technologies and architecture patterns, based on Chris Richardson's Microservices Patterns. This project includes a Java/Kotlin backend, React-based admin frontend, Kotlin Android app, Kubernetes deployment, and DevOps automation.
This monorepo demonstrates a complete microservices-based food delivery platform — covering customer ordering, restaurant/vendor management, rider delivery coordination, and payment processing — following best practices in scalability, observability, and cloud-native design.
- Microservices-based backend: Spring Boot (Java + Kotlin)
- Frontend admin portal: React + TypeScript
- Android mobile app: Kotlin + Jetpack
- Service communication: REST, Kafka/RabbitMQ
- Authentication: Keycloak + JWT + OAuth2
- Orchestration: Kubernetes + Helm + GitHub Actions
- Event-driven: SAGA, CQRS, Event Sourcing
