A multi-role learning platform with learner, instructor, and admin dashboards, course delivery, assessments, progress tracking, certificates, learning paths, analytics, AI content workflows, and an embedded multi-agent classroom flow. I worked on the backend API structure, role-based product flows, analytics-heavy interfaces, S3-compatible file storage, Celery jobs, and OpenMAIC classroom integration. The storage layer uses the S3 API shape, with Garage locally and AWS S3 as the production target, so object storage can move between self-hosted and managed infrastructure without rewriting the file layer.
