In February 2025, Mikhail Roytman focused on backend development for the openedx/edx-platform repository, addressing a critical issue in exam scheduling for non-LTI proctoring courses. He reintroduced the original due date calculation logic for exams powered by the edx-proctoring plugin, ensuring consistent behavior across courses published before and after the edx-exams microservice release. By carefully preserving the existing logic for LTI-based proctoring, he avoided potential regressions in those workflows. His work, implemented using Django and Python with an emphasis on API integration, was thoroughly documented to support future audits and ongoing development of the edx-exams microservice.
