AI Chatbot Developer Needed for Prototype

I am looking for a developer to help me put together an AI chatbot prototype using an LLM API. We have the basic idea and mainly need someone who can take it from concept to a working demo without overcomplicating things. The chatbot should be able to have a normal conversation with the user and keep track of the conversation context. What I am looking for: -The initial version should include: -A simple chat interface -Integration with OpenAI, Claude, Gemini, or a similar LLM -Conversation history/context -A system prompt -Basic error handling -New conversation/reset option -Basic backend/API setup -Streaming responses if it can be done easily -Simple setup instructions I'm not looking for authentication, analytics, complex UI, RAG, or other advanced features at this stage. The main thing I want is a clean working prototype that we can build on later. Technology Preferences: I’m flexible on the stack. I’d be comfortable with something like: -Python / FastAPI -Node.js -React -OpenAI / Claude / Gemini APIs If you have a preferred approach for a small project like this, feel free to suggest it. Project Deliverables: -Working chatbot -LLM integration -Conversation context -Source code -Basic setup instructions -Short walkthrough/demo I expect this to be a relatively small piece of work. The hourly rate for the project is $50/hr. If things go well, I may have some follow-up work around the chatbot and other AI features.
