About this gig

Template websites become limiting when your business needs dashboards, user accounts or external systems. I will develop a responsive full stack webapp built around how your team works.


Your product will combine a clean frontend with the backend logic, database and integrations needed to complete real tasks. It can be

  • a portal
  • booking system
  • internal dashboard
  • customer platform.


What you can receive:

  • Responsive frontend for mobile, tablet and desktop
  • Secure forms, user authentication and role-based access
  • Database design and backend development
  • Admin dashboard and content controls
  • API integration with approved third-party services
  • Error handling, testing and deployment
  • Organized source code and handover documentation


Each package has fixed limits for screens, roles and integrations. Hosting, paid APIs and subscriptions are not included unless stated in your custom offer.


Send your feature list, preferred technology, reference websites and design files. I will review the scope, identify dependencies and recommend the right package before development starts.
