Project Overview

Developed a comprehensive payment system using microservices architecture with Angular frontend and Python backend services. The system is fully containerized with Docker and deployed using Kubernetes with automated CI/CD pipelines.

Architecture

Frontend

Framework: Angular 15+
Features: Real-time payment processing, transaction history, user dashboard
Deployment: Nginx container with optimized build

Backend Microservices

Payment Service: Python FastAPI for payment processing
User Service: Python Django for user management
Notification Service: Python Flask for alerts and notifications
Gateway Service: API Gateway for routing and authentication

Infrastructure

Containerization: Docker containers for all services
Orchestration: Kubernetes cluster management
Service Mesh: Istio for service-to-service communication
Database: PostgreSQL with Redis caching

CI/CD Pipeline

Automated Testing

Unit tests for all microservices
Integration testing with pytest
