About this gig
I build production grade AI chatbots, RAG systems, and LLM agents using Claude and OpenAI APIs, backed by a track record of 20+ completed freelance projects across healthcare, legal, and e-commerce domains. My focus is retrieval grounded chatbots that cite their sources instead of hallucinating, and full stack applications where the AI is wired into a real backend, not a demo.
What I Offer:
- Custom Chatbot Development: RAG based assistants for customer support, internal knowledge bases, and healthcare or legal document Q&A, grounded in your own data with citations
- Integration: Backend and frontend integration using FastAPI, Node.js, React, and Next.js, deployed on AWS with Docker
- Natural Language Processing: LangChain and LangGraph pipelines with structured tool calling, not just prompt wrapping
- Ongoing Support: Bug fixes, prompt tuning, and feature additions after launch
Chatbots:
- Website RAG chatbot integration with citation grounded answers
- Slack bot for internal team workflows
- Voice enabled assistants using browser based speech input
- Scheduling and booking agents with tool calling (built one for a real family clinic)
Tech:
- LangChain and LangGraph
- Claude API and OpenAI API
- Chroma

I am a full stack developer and AI engineer with four plus years shipping software to production, not just demos. Expertise covers LLM integration, AI agents, and RAG systems using LangChain, LangGraph, and Claude and OpenAI APIs, backed by React, Next.js, Node.js, and PostgreSQL.
My services include RAG chatbots on your own data, AI agents that call tools and take real actions, full stack apps with AI built in, and computer vision or data extraction pipelines.
I am available 24/7 and happy to set up a quick Zoom call early on so we can walk through your requirements and start drafting.

FAQ
What is a RAG chatbot and why do I need one instead of a regular chatbot?
A regular chatbot answers from what the AI model was trained on, which means it can guess or make things up when it does not know something. A RAG chatbot searches your own documents, website content, or database first, then answers using that information and can show where the answer came from. If
Which AI models do you work with?
Mainly Claude and OpenAI's GPT models through their official APIs. I choose based on what fits your budget and use case rather than defaulting to one provider.
Can you connect the chatbot to my website or app?
Yes. I build the backend using FastAPI or Node.js and can integrate it into an existing website, a React or Next.js frontend, or expose it as an API your team can call from anywhere.
Do you build voice assistants too?
Yes, I have built voice enabled assistants using browser based speech input. If your project needs phone call handling through a specific voice platform, tell me which one before ordering so I can confirm it is something I can deliver.
