I will build a full stack web app with backend, user authentication and ai integration
Saúl Pérez
Über diesen Service
Most web developers build you a landing page and call it a web app.
I build complete full-stack applications - real frontend, real backend, real database, ready to ship to real users.
WHAT YOU GET
- Custom frontend (React or JavaScript)
- Backend REST API (Node.js or FastAPI)
- JWT authentication system
- Admin dashboard and role-based access
- AI integrations (chatbots, automations)
- Database design with PostgreSQL or Supabase
- Stripe payment integration
- Deployment-ready setup
- Clean, scalable code you fully own
WHY IT WORKS
I built Vyndra (vyndra.pro) - a production platform with dashboards, auth, REST APIs and AI. You get real product-level development.
PERFECT FOR
- SaaS MVPs and startup founders
- Custom internal tools
- AI-powered web applications
- Businesses replacing manual processes
Stack: React - Node.js - FastAPI - PostgreSQL - Supabase - Stripe
Tell me what you are building. I will tell you if I can ship it.

FAQ
Do you use templates or page builders?
No. Everything is custom-built from scratch. No WordPress, no Webflow, no drag-and-drop tools. Clean code that you fully own.
Is hosting included?
A: Hosting is not included, but I offer a complete production setup (VPS configuration, SSL, security hardening and deployment) for just $40 + the VPS cost. Your site will be fully ready to go live.
Can you integrate AI into my website?
Yes. I can add chatbots, content generators or smart forms. You'll need your own API key (OpenAI, Anthropic, etc.)
What if I need more pages than the package includes?
You can add extra pages as an add-on ($15 per page).
Do you offer support after delivery?
Yes. Revisions are included in every package. After delivery I offer a bug-fix window. Additional revisions cost $25 each. Extended support available on request.
