Zain Ul Abdin
About this gig
Build reliable AI agents and multi-agent systems with LangGraph for real business use cases.
I develop custom AI agents that can reason, call tools and APIs, use memory, retrieve knowledge, process data, and execute multi-step workflows. Depending on your project, I can build a single LangGraph agent, an autonomous AI agent, or a coordinated multi-agent system.
What I can build:
- LangGraph and LangChain agents
- Single-agent and multi-agent systems
- Tool/API calling and workflow orchestration
- RAG-enabled agents and knowledge workflows
- Memory, state and human-in-the-loop logic
- Database and external service integrations
- FastAPI backends and production APIs
- Docker/cloud deployment and production setup
Supported models include OpenAI, Claude, Gemini, Azure OpenAI, AWS Bedrock, Vertex AI, Llama and Mistral.
I focus on clean architecture, reliable execution and production-ready deliverynot just demos.
Please message me before ordering for complex, multi-agent or enterprise deployments so I can recommend the right scope and package.

FAQ
What types of AI agents can you build?
I can build single AI agents, autonomous agents, multi-agent systems, research agents, RAG agents, tool-calling agents, data-processing agents, internal business agents and custom agentic workflows based on your requirements.
Do you build multi-agent systems with LangGraph?
Yes. I can build LangGraph multi-agent systems using supervisor-worker, planner-executor or custom orchestration patterns with shared state, tools, memory and controlled agent-to-agent workflows.
Which AI models and frameworks do you support?
I work with LangGraph, LangChain, CrewAI, OpenAI Agents SDK, AutoGen, Google ADK and related frameworks. Models can include OpenAI, Claude, Gemini, Azure OpenAI, AWS Bedrock, Llama, Mistral and others.
Can you integrate APIs, databases and external tools?
Yes. I can connect agents with REST APIs, databases, vector databases, internal tools, SaaS platforms and custom business systems. Complex integrations may require a custom offer.
Can you add RAG and business knowledge to the AI agent?
Yes. I can integrate RAG so your agent can retrieve information from documents, databases, knowledge bases or other business data while performing agentic tasks.
Do you provide production deployment?
Yes. Depending on the package or custom scope, I can provide FastAPI integration, Dockerization, cloud deployment, environment configuration and production setup. Kubernetes, CI/CD and advanced observability can also be handled through a custom offer.
Should I contact you before ordering?
Yes, especially for multi-agent systems, enterprise applications, complex API integrations or production deployments. Send me your use case, required tools, data sources and deployment requirements so I can recommend the right package.
