open.quiz

The problemThe problem

Learning platforms often tie a curriculum and visual identity to application code. Supporting a new subject or branded deployment can then require editing or forking the core product.

The solutionThe solution

open.quiz separates learning services from content modules. Learners get accounts, structured lessons, quizzes, and progress tracking; administrators can create or import curricula and customize the site's branding and themes. Portable .openquiz.json packages can include a theme and assets, with lesson modules optional. A single Node.js service can serve the built React frontend and Express API.

My contributionsMy contributions

• Independently developed Sprout's evolution into open.quiz, separating curriculum modules from the core learning services.
• Built the single-service deployment in which Express serves the production React app alongside the API.
• Implemented administrator-managed themes, learning material, and portable packages so deployments can adapt content and presentation without changing the shared core.
• Maintained contribution, conduct, security, and content-accuracy guidance for the open-source project.

Behind the projectBehind the project

Sprout was a team-built financial-literacy app from the Code the Dream practicum. I independently developed its evolution into open.quiz, a self-hostable platform for different subjects and visual identities. I built the platform's modular content, administrator customization, portable packages, and deployment workflow, and maintain its project guidance.

Engineering decisionsEngineering decisions

Curricula and presentation need to be portable without coupling either to application code. open.quiz packages keep theme, image assets, and optional lesson modules as separate parts, allowing content-only or themed experiences to move between installations. Administrators can also create and manage learning material in the app. On a fresh self-hosted installation, the first successful sign-in initializes administrator access; the included open.quiz instructional lessons are installed automatically, while example curricula remain opt-in.

TestingTesting

GitHub Actions runs frontend lint, tests, and builds; backend lint, coverage-enforced tests, and syntax checks; then browser journey checks. The documented npm run verify workflow also runs every Playwright project, including throttled-network and learn-flow latency runs.
