About this gig
I build production-ready AI agents with LangGraph, LangChain, Python, and FastAPI.
If you need an AI system that can reason through multiple steps, use tools, call APIs, keep memory, and complete real workflows, I can build it for your use case.
What I can build:
LangGraph AI agents
Stateful and multi-step workflows
Tool and function calling
API and database integrations
Memory and checkpoints
Multi-agent systems
MCP server/tool integration
Human-in-the-loop approval
FastAPI backend endpoints
Testing, error handling, and deployment support
Tech stack can include LangGraph, LangChain, OpenAI, Claude, Gemini, Python, FastAPI, MCP, PostgreSQL, vector databases, and REST APIs.
You will receive clean source code, setup instructions, and documentation.
Please message me before ordering so I can review your workflow, required tools, integrations, and deployment needs.

Q: What can a LangGraph AI agent do?
A: It can use tools and APIs, keep state or memory, follow multi-step logic, call external systems, and complete workflows instead of only replying with text.

A: Yes. I can build coordinated agents with different roles, routing logic, shared state, tool use, and validation steps when the project needs them.
Q: Can you integrate MCP servers or tools?
A: Yes. I can connect supported MCP servers or build tool integrations for APIs, databases, files, search, and other business systems.
Q: Which AI models can you use?
A: I can work with supported models from OpenAI, Anthropic Claude, Gemini, and other suitable providers depending on your use case.
Q: Will I receive the source code?
A: Yes. Source code is included in the packages shown. I also provide setup guidance and documentation based on the selected package.
Q: Should I message you before ordering?
A: Yes. Please send your use case, required tools or APIs, data sources, preferred model, and deployment needs so I can confirm the correct package.
