I will build a custom ai agent rag chatbot or n8n automation for your app
About this gig
I add AI that actually does the work not a toy chatbot.
I build production AI features into the app you already run:
- Agents that plan, search your data, and take multi-step actions
- RAG assistants grounded in your docs/site, with citations (no hallucinations)
- Custom MCP servers that connect Claude Desktop, IDEs, or your agents to your tools and data
- Streaming, error handling, deployed live
Proof, not promises: a live agent demo (DocChat Agent) and an open-source MCP server are in my portfolio links on request.
Stack: Next.js, TypeScript, Python/FastAPI, Vercel AI SDK, OpenAI / Gemini / Claude. You keep your own API keys.
Message me with what your app does and what you want the AI to handle I'll tell you exactly how I'd build it.

FAQ
Q: Do I need to pay for AI usage?
A: You bring your own API key (OpenAI/Gemini/Claude) — standard practice, and it keeps usage in your control. I build and wire everything.
Q: Can you add this to my existing app?
A: Yes — that's the main thing I do. I drop the AI into the product you already run.
Q: What's the difference between an agent and a chatbot?
A: A chatbot replies. An agent plans, runs its own searches/tools, and completes multi-step tasks — I can show you a live one.
