I will build a fullstack ai powered web application with react node and fastapi


About this gig
I build complete web applications frontend, backend, database, and AI as one connected product, not disjointed pieces. If you need an app that's actually intelligent, not just good-looking, this is that gig.
I'm a backend and AI systems engineer building production-grade apps with React, Node.js, FastAPI, MongoDB, and Redis, with AI (Gemini/OpenAI) woven into core functionality, not bolted on.
Recent work: an AI analytics platform converting natural-language queries into structured insights and live visualizations, and a distributed ticket-booking system handling 465+ req/sec with zero data loss under load. Same engineering rigor on every project clean architecture, proper error handling, deployable code.
What you get:
- Full frontend (React) + backend (FastAPI/Node.js) built to spec
- AI integration: chatbots, natural-language search, content generation, automated data analysis
- Database design (MongoDB/Redis) matched to real access patterns
- Clean, documented code no black box
- Deployment support (Docker, Render, Azure)
Ideal for: startups needing an MVP with real AI functionality, founders wanting a fast working prototype, or anyone burned by a "full-stack dev" who only does frontend.

FAQ
Do I need my own API key for the AI features?
Yes, you'll need a Gemini or OpenAI key; I'll guide you through getting one if you don't have it.
Can you work with an existing codebase instead of starting fresh?
Yes, message me with details before ordering so I can scope it accurately.
What if my project needs more than what's listed in Premium?
Message me first — I'll send a custom offer so scope and price match exactly.
