I will build an ai feature or chatbot using gpt or custom llm API


About this gig
Want to add AI to your product without guessing how to structure it? I build clean, ready-to-use AI modules from small smart features to full AI-powered web apps.
Instead of a quick hack or one-off script, I deliver maintainable code with clear logic, optional UI for testing, and a structure you can scale or extend later. Whether you just need an AI-powered feature or a complete standalone AI app, I make sure its built properly from the start.
- AI API + optional UI demo for instant testing
- Clean modular structure (not a throwaway prototype)
- From small feature to full AI web app both possible
- Scalable base ready for future vector DB / RAG upgrade
I work with GPT, Claude, LangChain, Pinecone, React, Node.js and FastAPI. The goal is simple deliver an AI feature that feels like a real product component, not an experiment.
Feel free to message me before ordering I can quickly suggest the best way to implement your idea.

FAQ
Can you build both small AI features and full standalone apps?
Yes - I can implement a single AI-powered feature or develop a complete AI web app with UI, backend, and optional vector DB.
Do I need to provide my own API key (OpenAI, Claude, etc.)?
For production use - yes. I can use my own key for development and testing if needed.
Is the solution production-ready or just a prototype?
Even in the Basic package I deliver clean structure. Standard and Premium are designed to be integration-ready.
Can you integrate Pinecone, Weaviate or other vector databases?
Yes - vector DB / RAG setup is available in the Premium package or as an add-on to Standard.
Should I contact you before ordering?
Yes - it helps define the right scope (small feature vs full app) and choose the best package or custom offer.
