Muna Rahman

Muna Rahman modernized the Discounts module in the Shopify/function-examples repository by implementing class-based filtering for Order, Product, and Shipping discounts during cart and delivery run generation. This work replaced outdated network-based discount logic, removing related code and dependencies to streamline the backend architecture. Using JavaScript, Rust, and GraphQL, Muna focused on improving the correctness and maintainability of discount application, ensuring discounts are only applied when the relevant class is present. The changes reduced the risk of incorrect discounts, simplified deployment, and lowered maintenance overhead. The scope was well-defined, with clear traceability through focused, well-documented commits for the release.
