During February 2025, Amir Mousazadeh focused on backend development for the Max-Eee/E-commerce-recommender repository, addressing a critical issue in the product listings feature. He identified and resolved a bug in the pagination logic by correcting the offset calculation, ensuring that the first page of product listings now starts at offset zero. This TypeScript-based solution improved the reliability and consistency of data retrieval across catalog pages, eliminating previous errors caused by incorrect offsets. Amir completed thorough code review and validation to prevent regressions, laying a stable foundation for future enhancements to the product listing functionality within the e-commerce recommender system.
