PROFILE

Marcos

Michael Rigoli developed robust backend features for the edx/learning-assistant and edly-io/edx-platform repositories, focusing on data reliability, security, and maintainability. He implemented persistent, course-scoped chat history with feature flag controls, refactored message persistence logic, and improved test coverage using Django and Python. Michael also unified JWT token management across CMS and LMS, consolidating logic into a single core library and removing redundant dependencies. His work included database migrations, enhanced audit trail validation, and CI/CD hygiene, resulting in more consistent configuration and reduced maintenance overhead. The depth of his contributions reflects strong backend engineering and thoughtful system design.

January 2025: Delivered Unified JWT Token Management Core for edx-platform, consolidating JWT handling into a single self-contained library, centralizing tests, and aligning token configuration across CMS and LMS. Removed the edx-token-utils dependency and migrated token logic to openedx.core.lib, with updated environment settings, import paths, and documentation. Completed test/CI hygiene (make compile-requirements, test fixes) and refreshed CMS defaults for token signing. Result: reduced maintenance, fewer configuration drifts, and a single source of truth for token behavior across platforms.

2024-10 – EdX Learning Assistant: Delivered persistent chat history with toggle and API save (save_chat_message), with course-run context to scope history across sessions. Introduced feature flag learning_assistant.enable_chat_history for controlled rollout. Refactored message persistence logic into its own method and improved test coverage for CourseChatView, including fixing course id vs course key mismatch. Business impact: enhanced UX with cross-session chat history and richer analytics per course run, plus safer rollout via feature flag.
