Worked on the edx/ecommerce repository to deliver mobile payments for new course offerings, focusing on backend development and payment integration. Developed a feature that enables the creation of mobile seats for courses, with optional support for generating iOS App Store products. The implementation included updates to backend serializers to handle mobile seat creation and updates, and integrated with the App Store API, all gated behind a feature flag to ensure a controlled rollout. Utilized Python for API development and backend logic, supporting new monetization pathways for courses while maintaining safe deployment practices and enhancing the e-commerce platform’s extensibility.
