Aisha and her friends arrive at their first hackathon feeling nervous because they do not know what to expect. They scan the QR code, read the 3-hour schedule, and realize the event is structured in small, manageable steps with optional bonus challenges instead of one overwhelming sprint.

During the build, the team gets a Chaos Card to add responsive design. They choose to attempt it, complete it, and see their bonus points reflected in the dashboard without any manual tracking from volunteers. When demo time comes, their submission and judging criteria are already organized, so they can focus on presenting instead of scrambling.

After the event, they receive a clear results page and certificates, while the Tech Club gets a polished report showing participation, scores, and engagement. The event feels more professional, easier to run, and more welcoming to beginners, which makes it more likely that students return for future technical activities.

  • Queue bulk certificate generation to avoid timeouts during results publishing.

Potential Challenges

  • Risk: volunteers forget to trigger a Chaos Card on time. Mitigation: provide automated alerts and a visible release checklist.
  • Risk: beginner teams feel pressured by bonus challenges. Mitigation: keep cards optional and clearly label them as bonus-only.
  • Risk: scoring disagreements between judges. Mitigation: use weighted rubrics, locked criteria, and tie-break rules.
  • Risk: unstable venue internet disrupts live operations. Mitigation: add offline-friendly check-in and local fallback timers.
  • Risk: duplicate or incomplete team registrations. Mitigation: validate required fields, enforce uniqueness, and provide organizer review before approval.

Build a responsive web app called ChaosLab for running beginner-friendly mini hackathons with timed optional challenge cards.

Core product:
Participants register teams of 2 to 4, view the event schedule and judging rubric, join a live 3-hour event, receive optional Chaos Cards during the sprint, submit project links, and view results/certificates after judging. Organizers create events, manage check-in, trigger timed announcements and Chaos Cards, and publish results. Judges score teams with weighted criteria and leave notes.

Primary screens and flows:
1. Public event landing page with agenda, rules, judging criteria, FAQs, and registration CTA
2. Team registration flow with validation for team size, required fields, duplicate team names, and waitlist support
3. Organizer dashboard with event setup, live timer, announcement controls, Chaos Card release controls, check-in list, and capacity indicators
4. Participant live event page showing current phase, countdown timer, released Chaos Cards, team status, and submission link area
5. Judge scoring page with list of teams, submission details, weighted scoring inputs, comments, and auto-calculated totals
6. Results page with leaderboard, winners, bonus points, and certificate download/share links

Data model:
Event, Team, Participant, Registration, Role, ChaosCard, ChaosCardAttempt, Submission, Judge, JudgeScore, Announcement, Certificate, AuditLog
Include fields for event timing, capacity, team size, card status, score weights, and result publication status.

Tech stack:
Use Next.js 14 with TypeScript, Tailwind CSS, shadcn/ui, PostgreSQL, Prisma, and NextAuth or Clerk for auth. Use Server Actions or a small REST API for mutations, WebSockets or SSE for live timer updates, React Query for client state, and a queue like BullMQ for certificate generation. Store files in S3-compatible storage. Use PostHog for analytics and SendGrid for email.

Implementation requirements:
Make the UI mobile-friendly, accessible, and fast on campus Wi-Fi. Add role-based access control for organizer, volunteer, judge, and participant. Include seeded demo data for one sample event, 5 teams, 6 Chaos Cards, and sample scores. Add validation, empty states, error handling, loading states, and audit logging for critical actions. Provide polished UI with large countdown timers, clear color coding for statuses, and simple forms. Scaffold the database schema, main pages, shared components, and API routes or server actions needed for the full MVP.
