I will build an ai agent or automation system with langgraph and python


About this gig
Need an AI agent that actually does the work instead of just chatting? I build multi-agent systems in Python that plan, use your tools and hand back real output.
What I build:
- Multi-agent workflows with LangGraph: planner, worker and reviewer agents
- Tool use: your APIs, databases, files, spreadsheets and web search
- RAG assistants that answer from your own documents
- Memory, retries, logging and human-in-the-loop approval steps
- A simple UI or API endpoint so your team can actually use it
- Local LLM setups with Ollama when data must stay on your machine
Models: OpenAI, Anthropic Claude, Gemini or open models. You keep your own API keys.
Tools: Python, LangGraph, LangChain, FastAPI, SQLite/Postgres, Docker.
What I need from you:
- What task should the agent do, start to finish
- Which tools, files or APIs it must reach
- An example of a good result
I start with a short plan and a working demo of the core loop, then build the rest in milestones. You get clean, documented code you can run yourself.
Message me with your use case and I'll tell you honestly whether an agent is the right tool for it.

FAQ
Which LLM do you use?
OpenAI, Anthropic Claude, Gemini or open models such as Llama and Qwen via Ollama. You use your own API keys, so you control cost and data.
Do I pay for API usage?
Yes, LLM API costs are billed by the provider to your own account. My price covers building the system.
Can the agent run on my own server?
Yes. I can deliver it as a Python package or a Docker container, including a fully local setup with Ollama.
Will my data stay private?
Yes. Your data is used only for your project. If privacy is critical, I can build a fully local pipeline with no external API calls.
Which package should I choose?
Basic for one focused task. Standard for a multi-step workflow with your tools. Premium when your team needs a UI, storage and reliability. Message me and I'll recommend one.
