I will build an ai chatbot, rag system or llm agent with openai and langchain
Faizan Javed
Sobre este Serviço
Need an AI feature that works in production, not a demo?
I build chatbots, RAG systems and LLM agents that connect to your real data and run reliably. Typical projects: a support bot trained on your docs, an internal assistant over company knowledge, or an agent that automates a multi-step workflow.
What I work with:
OpenAI, Claude and open-source models
RAG pipelines with vector databases (Pinecone, pgvector, Chroma)
LangChain and LlamaIndex orchestration
Python, FastAPI and Django backends
Web chat widgets, Slack and WhatsApp delivery
Basic covers a single-purpose chatbot on a small document set. Standard adds a full RAG pipeline with your data sources and a web interface. Premium covers multi-step agents, tool calling and deployment.
I have shipped AI systems in healthcare, recruitment and financial research, including agentic pipelines and RAG architectures.
Message me with your data sources, expected volume and where the AI needs to live before ordering, so we can agree scope.

Perguntas frequentes
Do I need my own OpenAI or Claude API key?
For production you should use your own API key so you control billing and data access. I can build and test on a development key, then hand over full setup instructions, or walk you through creating the account.
Can it answer from my private company data?
Yes. That is what the RAG packages are for. Your documents are indexed into a vector database and the model answers only from that content, with citations back to the source so you can verify every answer.
Will I receive the source code?
Yes. Source code is included in every package so the agreed work can be maintained and extended.
What should I send before ordering?
Send your page list, designs or references, required features and any existing project details. I will confirm the scope and suitable package through Fiverr.
