I will build a custom ai agent with langgraph and API integrations


About this gig
Need an AI agent that does more than generate basic text?
I build custom AI agents and intelligent workflows that connect GPT, Claude, or Gemini with your existing applications, APIs, databases, and business tools.
I can help you build:
- Multi-step AI agent workflows
- API and third-party tool integrations
- Database and vector database connections
- RAG and document-based assistants
- Tool calling, routing, memory, and state management
- Structured outputs and validation
- Human approval steps and safety guardrails
- Error handling, logging, and deployment support
My typical technology stack includes Python, LangGraph, LangChain, FastAPI, OpenAI, Anthropic Claude, Gemini, PostgreSQL, Supabase, Pinecone, Qdrant, and cloud platforms.
Every project includes a clearly defined scope, clean implementation, testing, source code, and documentation based on the selected package.
This Gig is ideal for internal assistants, research agents, sales and operations workflows, document processing, customer support, and business automation.
Please message me before ordering. Share your use case, current system, required integrations, expected output, and deadline so I can confirm the right package and deli
