Ismail Seghiri worked on the alma/alma-php-client repository, focusing on refactoring the FeePlan component to support a transition from fixed to dynamic fee calculations. He deprecated the customer_fee_fixed property by initializing it to zero and clearly documenting its deprecation, ensuring that future development aligns with evolving pricing strategies. Using PHP, Ismail emphasized code documentation and refactoring to reduce technical debt and prepare the codebase for more flexible fee structures. His work laid the foundation for alternative fee calculation methods, providing clear communication to other developers and maintainingers while enhancing maintainability and adaptability within the client’s business logic.
