I will be your next js developer for a production ready saas web app with ai
Fuat S.
About this gig
Turn your idea into a production-ready web app - built with Next.js, a solid API layer and AI features that actually help your users.
Off-the-shelf tools stop working once your business needs custom logic, a real database or AI that understands your data. I build full-stack Next.js apps with TypeScript and add AI where it creates real value - not just for show.
WHAT I CAN BUILD
Custom web apps and internal tools with Next.js and TypeScript- API integrations and backend logic (Node.js, REST/GraphQL)- Database design (Postgres, Supabase, or your stack)- AI features: chat, content generation, data processing with OpenAI, Claude or Gemini- Authentication, dashboards and admin panels
WHY AI INTEGRATION MATTERS
Example: an AI chat assistant answering customer questions from your own data, cutting support replies. Or AI content generation saving your team hours of writing each week.
MY PROCESS
Scope and stack confirmation, build with test data, QA pass and bug fixes, documentation and handover.
Swiss-based, privacy-focused, available in English or German. Message me with your idea before ordering.
Live demo: demo-saas-inbox.vercel.app

Swiss-based developer for automation and AI-powered apps.

Every build is scoped clearly, tested with real or realistic data, and handed over with documentation - not a throwaway prototype. Support in English or German.

FAQ
Do you build the backend too, or only the frontend?
Both. I build the Next.js frontend and the API/backend logic, and connect the database you choose or recommend one for your use case.
Can you add AI features to an existing web app?
Yes. I can add AI features like chat, content generation or data processing to an app you already have, as long as I get access to the relevant code or API.
What AI providers do you use?
Typically OpenAI/GPT, Claude or Gemini, depending on your budget and requirements. I document usage costs so there are no surprises.
Is this a working product or just a demo?
A working product. Every build is tested with real or realistic data before handover, not a throwaway prototype.
How long does development take?
Timelines depend on scope: a single page or feature typically takes 4 days, a full multi-page app around 7 days, and a complete SaaS build with AI and API/database integration around 14 days.
