The Taxation System is a cloud-native solution developed for a national government, utilizing AWS CDK (TypeScript) for infrastructure automation. The system employs API Gateway and AWS Lambda for serverless API management, ensuring scalability and cost-efficiency. DynamoDB is used as the NoSQL database, enabling fast and scalable storage of tax-related information. SendGrid handles email communication, while AWS Cognito with Amazon Verified Permissions ensures secure user authentication and role-based access control. S3 Buckets are used for file uploads and document storage.

Key highlights:

Scalability: Serverless design with AWS Lambda and DynamoDB, providing automatic scaling.

Security: Robust user management with AWS Cognito and verified permissions.

Automation: Infrastructure as code managed through AWS CDK, streamlining deployment.

This system enhances the Nigerian Government’s taxation process, providing a secure, efficient, and scalable solution for tax management.
