I will build a custom web app or saas with react, next js and node


About this gig
Need a real, custom-coded web app or SaaS not a template, and not a no-code prototype you'll outgrow? I'm Fieldstone Labs, and I build production web applications with clean, modern code you fully own.
I work full-stack with React, Next.js, Node, and TypeScript (plus Supabase / Postgres), building fast, scalable products with proper auth, payments, and APIs.
WHAT I BUILD
- Custom web apps and SaaS platforms
- Dashboards, admin panels, and client portals
- Auth, Stripe billing, and role-based access
- REST / GraphQL APIs and third-party integrations
- Rescue and scaling of existing codebases
HOW I WORK
- Clear scope and milestones before we start
- Clean, documented, maintainable code no lock-in
- Regular progress updates and demos
- Deployed and handed over, with full source code
New to Fiverr, but not new to shipping production software. Message me before ordering with what you're building, and I'll recommend the right stack and a realistic plan. Let's build it.

FAQ
What tech stack do you use?
React and Next.js on the front end, Node.js/TypeScript on the back end, with Supabase or Postgres. I'll pick what fits your product best.

100%. You get the full source code, documented, in your own repo, no lock-in and no dependency on me.

Yes. Share the repo and I'll review it, then quote the fixes, features, or scaling work as a custom offer.
Will you deploy it for me?
Yes, I deploy to Vercel, Netlify, or your preferred host, and hand over everything set up and running.
