CourseFlow

A full Udemy-style learning platform — catalog, curriculum builder, exams and certificates — shipped solo in seven months.

What it is

CourseFlow is a complete LMS. Students browse the catalog, enrol in courses, work through chapter-by-chapter lessons, sit exams and download certificates. Instructors build courses through a drag-and-drop curriculum editor and a TipTap rich-text lesson surface. Admins manage roles, categories and content.

Built solo on Next.js 15 (App Router, Turbopack) over Supabase. The data model is the proof point — relational RBAC across student / teacher / admin, courses → chapters → lessons, enrolment-and-progress, exams, certificates — all under one schema, with migrations tracked in the repo.

What it does

5 signals

  1. 01 · Catalog
    Course catalog and learner experience

    Categories, course cards, course-detail pages, chapter-by-chapter lessons with progress tracking, enrolment flow. App-router with locale-aware routes from the start — next-intl drives i18n end-to-end.

  2. 02 · Builder
    Drag-and-drop curriculum editor

    Instructors structure chapters and lessons with dnd-kit; lesson bodies are authored in a TipTap surface with images, links and rich-text. The teacher dashboard and admin editor share the same primitive.

  3. 03 · RBAC
    Three-tier roles with route-level enforcement

    Student, teacher and admin roles enforced at Next middleware + Supabase RLS. The instructor onboarding flow ('become-instructor') and admin promotion are first-class. A small script keeps admin-role assignment auditable.

  4. 04 · Exams
    Exams, questions and signed certificates

    API routes for exams, questions, attempts and certificates. After completion the platform issues a certificate tied to the enrolment record — closing the loop from catalog browsing through finished course.

  5. 05 · AI-native
    Schema-aware AI in the build loop

    Supabase MCP gives the AI assistant direct read access to the live schema — Claude and Cursor see the same tables as the running app. Kombai handles AI-assisted UI generation. A modern solo development loop.

Note

A repo opening is queued behind a secrets-hygiene pass — keys committed during the build need rotating and scrubbing before the source goes public. Happy to walk through the architecture in the meantime.

Open to Senior / Staff engineering roles and selective freelance — production AI, platform, and full-stack work.
