Gig Summary

About this gig

Looking for a full stack developer to build your AI web app or SaaS product?


FuzionDev develops custom web applications using Next.js, React, TypeScript and Node.js. We connect frontend, backend, databases and AI integrations around your business workflow.


What we can build

  • Responsive dashboards, admin panels and client portals
  • Authentication, user roles and database integration
  • AI chat, text generation and third-party APIs
  • Stripe payments and subscription workflows
  • Testing, deployment and documented source-code handover


How we work


We define deliverables before development, share progress at milestones, and include a bug-fix period after delivery.


Choose your starting point

  • Basic: One frontend screen for your application
  • Standard: One functional AI feature
  • Premium: A focused AI MVP


Have a prototype built with Claude Code, Codex, Lovable or Replit? We can review it and quote further development separately.


Hosting, AI usage and third-party subscriptions are excluded.


Send your requirements, designs or existing application. We will recommend the right scope.

    This was one of many milestones I’ve had with this developer. Very patient and delivered my product with speed and quality. Was very quick with small tweaks we had along the way and understood my requirements and went above and beyond expectations. 10/10 would recommend.
