Technical Approach

Architecture Design

1. Microservices Architecture:
   • Designed a modular microservices system to allow independent scaling of key functionalities such as payments, subscription management, and analytics.
   • Leveraged containerization using Docker and Kubernetes for ease of deployment and scalability.
2. Tech Stack:
   • Frontend: Flutter for cross-platform mobile development (iOS, Android).
   • Backend: Node.js and Express.js for API management.
   • Database: PostgreSQL for relational data and Redis for caching.
   • Payment Gateway: Stripe for secure and global payment processing.
   • Cloud Infrastructure: AWS (EC2, S3, Lambda, RDS).
3. Security:
   • End-to-end encryption for data transmission.
   • Role-based access control (RBAC) for secure handling of admin, vendor, and customer operations.
   • Compliance with GDPR standards for data privacy.
