I will build your ai web app or saas mvp with react, nodejs and python


About this gig
Need a working AI-powered product, fast? I build full-stack web apps with React or Vue on the front, Node.js or Python on the back, and OpenAI / Claude / DeepSeek wired in properly.
What you get:
- A clean, responsive frontend (React, Next.js or Vue)
- Backend API (Node.js, Express, NestJS or Python: Flask, FastAPI, Django)
- PostgreSQL or MongoDB database, user login
- AI features: chat, summarization, content generation, image input
- Stripe payments and deployment if needed
Experience: 7+ years. I built the backend and admin for AI Mate, a GPT-powered chatbot app supporting 50,000 users, with streaming replies, multiple AI models and usage-based credits. I led the architecture of a clinical MRI diagnostics platform and built an EdTech SaaS used by multiple institutions.
Quick delivery, daily updates, clean code you own fully. Message me with your idea and I'll suggest the simplest stack that ships.
