You will get AI Chat with File Upload & LLM | React, Next.js, TypeScript
Project details
You will get a production-ready AI chat application with file upload support and seamless LLM integration, built using React, Next.js, and TypeScript. This project is designed for startups, SaaS products, and internal tools that need a clean, fast, and scalable AI chat experience.
I focus on real-world usability, not demos. Your app will include a modern chat UI, secure API integration, proper state management, and a solid frontend architecture that’s easy to extend (RAG, memory, tools, or multi-model support later).
With 4+ years of experience building live SaaS dashboards and AI interfaces, I ensure clean code, optimized performance, and a polished user experience. The result is a reliable AI chat system that feels smooth, intuitive, and ready for real users—not a hacky prototype.
Perfect if you want:
A ChatGPT-like UI for your product
File upload + context-aware responses
A scalable frontend foundation you can grow on
Clear communication, on-time delivery, and quality you can ship with confidence.

About Kankana
Full-Stack Engineer (Frontend-Heavy) | React, Next.js, Node.js, APIs
Kolkata, India - 7:25 pm local time
maintaining, and scaling production web applications.
I help teams and founders who need:
• A strong React / Next.js frontend
• Reliable backend APIs and data flow
• Someone who can take ownership of an existing codebase and keep it stable
My core strength is frontend (React, TypeScript, performance, UX),
but I regularly work end-to-end — from UI to APIs, auth, and databases.
Recent work includes:
• AI & SaaS platforms with real-time interfaces
• Dashboards and data-driven applications
• Full-stack features integrating React frontends with Node.js / Python APIs
Tech I work with daily:
Frontend: React, Next.js, TypeScript, Tailwind, Material UI, Shadcn UI
Backend: Node.js, Express, Python (Flask), REST APIs, Auth
Data: MongoDB, Firebase Firestore, SQL (basic)
Tooling: Git, CI/CD, Docker (basics), Vercel
I’m especially good at:
• Understanding existing codebases fast
• Fixing bugs and performance issues
• Shipping features safely without breaking production
• Long-term maintenance and ongoing development
If you need a dependable developer who can handle frontend-heavy full-stack work,
I’m happy to start with a small task or trial.
