    • Develop a web-based admin dashboard for the super admin to:
      • Monitor sales and ticket numbers across stores.
      • Announce results for ticket draws.
      • Generate PDF reports and visualize sales analytics (daily, weekly, monthly).
    • Implement functionality to track store performance and credit transactions.
  3. Result Checking & Security:
    • Implement a QR code scanning feature to allow customers to check ticket results in-store.
    • Ensure secure transactions for credit management and result verification.
  4. Integration & Testing:
    • Integrate the app with a POS-style printer for ticket printing.
    • Ensure smooth functionality across all modules (ticket sales, printing, credit management, result checking).
    • Conduct thorough testing to ensure the app is bug-free and performs well under various scenarios.
  5. Collaboration & Documentation:
    • Collaborate with the design team to implement the provided design resources.
    • Document the codebase and provide clear instructions for future maintenance.

Requirements:

Technical Skills:

    • Familiarity with data visualization libraries (e.g., Chart.js, D3.js) for sales analytics.
    • Experience with PDF generation libraries for report creation.
  • Version Control:
