QuizMaster is a platform built for both learners and educators. You can take quizzes and mock tests to strengthen your knowledge—or become a creator and share what you know with the world. Learning here isn’t boring or passive; it’s interactive, competitive, and genuinely fun.
How to Test QuizMaster
Test login: login via google directly
What I Built
I’m a tech enthusiast who strongly believes that learning works best when it feels like a game, not a chore. QuizMaster started with one simple question:
- What if testing knowledge felt as engaging as playing a game?
- That idea turned into a full-fledged platform where:
- Learners can practice through quizzes and mock tests
- Creators can design quizzes with ease
- Gamification keeps users motivated and coming back
- Every feature—from the intuitive quiz creation flow to score-based engagement—is designed with real users in mind. This isn’t just another side project. It’s a living product, shaped continuously by feedback and experimentation.

My Experience with GitHub Copilot CLI
Building a full platform solo can be overwhelming—remembering syntax, designing features, debugging, and deploying all at once takes serious time.
That’s where GitHub Copilot CLI completely changed the game for me.
With Copilot CLI:
Building a production-ready platform solo is overwhelming—context switching between syntax, UI, logic, debugging, and deployment eats time fast.
GitHub Copilot CLI removed that friction.
With Copilot CLI, I was able to:
Go from idea → production in just 20 days
Experiment freely without getting stuck on implementation details
Learn and apply new concepts almost instantly
Real examples of Copilot CLI in action:
Integrated subjective questions into mock tests
→ Copilot CLI generated the core logic, which worked after testing.
Built a complete blog and study material system
→ From structure to content flow.
Linked blogs with mock tests for better content discovery
→ Seamless cross-referencing.
- Fixed PWA issues, navigation, and layout entirely via CLI prompts. When ever I feel stuck this UI change would not be possible a detailed prompt with cli helped me resolve those UI issues.
Few More Feature Examples that are totally build by github cli only:
- Quiz unlock codes
- Bookmarking for quizzes, creators, and content
- Logged-in-only content visibility
- integrating start and end date quiz feature
- enhancing the whole UI
- building the blog analytics and admin dashboard
- Guided me through production deployment and configuration
- My website was totally in dark mode, copilot used tailwind css and integrated the whole light theme in my project.
- Copilot CLI felt less like a tool and more like a tireless pair-programming partner—helping me focus on product thinking instead of boilerplate and guesswork.
- It helped me setup my ngnix configuration file from start , which I was not aware of even how to start with.
🔒 Security Features (which co-pilot cli build with different models) (used sonnet, claud opus and various different models with act and plan to achieve this goals)
- JWT Authentication: Secure token-based auth
- bcrypt: Password hashing (12 rounds)
- Helmet.js: Security headers
- Rate Limiting: 100 requests/minute general, 10/minute auth
- Judge0 safety (Mock Interviews): backend-only access, strict run/submit caps, cooldowns, per-session rate limits, bounded polling, and a circuit breaker to fail safe during provider issues
-
Mock interview publish safety (backend): cannot publish a
MOCK_INTERVIEWquiz without configured interview items; coding items are capped at 4 - Hidden tests safety: hidden test cases are never returned to end-user mock interview UI; system coding questions are read-only
- Parameterized Queries: SQL injection prevention
- CORS: Configured for frontend origin
- Input Validation: express-validator on auth, quiz, attempt, feedback, user, creator-request endpoints (type, length, format)
- Input Sanitization: Trim and escape on string inputs; search and text fields length-limited (e.g. question text max 5000, search max 200) And I don't have to do much, I have to just ask the CLI to think of as an expert in that domain and he becomes that and writes very clean, concise and robust code.
QuizMaster exists today as a real, live product because GitHub Copilot CLI removed friction from the development process. It allowed me to focus on ideas, creativity, and user experience instead of being blocked by implementation hurdles.
This project proves how powerful developer tools can be when paired with passion and persistence.
This challenge helped me go from asking Copilot for help to building a tool that helps others.
Thank you, GitHub and DEV, for this opportunity 🙌
