Risks

1. SQLite for Database: The use of SQLite poses a high risk due to scalability issues.
2. Hardcoded Tax Rules: This presents a medium risk as it affects maintainability.
3. Tax Calculation in Code: Conducting tax calculations within the codebase introduces a medium risk, potentially leading to performance issues.

Improvements

1. Database Migration: Transition to a more robust database system such as SQL Server or PostgreSQL to enhance performance and prepare for production environments.
2. Logging and Monitoring: Implement comprehensive logging and monitoring solutions to improve system observability and reliability.
3. Decoupling Tax Rules: Utilize a rule engine such as Microsoft Rule Engine to decouple tax rules from the codebase, thereby improving flexibility and maintainability.
4. Distributed Caching: Integrate a distributed cache solution like Redis to manage caching efficiently, which will significantly enhance performance.
