Worked on the openedx/edx-platform repository to address exam scheduling consistency for non-LTI proctoring exams. Focused on backend development using Django and Python, the developer reintroduced the original due date calculation logic for exams powered by the edx-proctoring plugin. This change ensured that courses published before and after the edx-exams microservice release maintained consistent due date behavior, while the logic for LTI-based proctoring remained unchanged to prevent regressions. The work involved careful API integration and thorough documentation of the update’s impact, supporting future microservice releases and audits. The contribution centered on a targeted bug fix rather than new features.
