Belton M
About this gig
Are you looking to automate complex business workflows using AI? I specialize in building production-grade multi-agent systems using LangGraph, LangChain, and the latest LLM APIs.
What I build:
- Multi-agent pipelines with LangGraph orchestration
- RAG systems that answer questions from your documents or database
- AI agents that search the web, process data, and make decisions autonomously
- LLM-powered APIs using FastAPI ready to integrate into your existing product
- End-to-end systems with error handling, logging, and Docker deployment
Why work with me:
- I have delivered production AI systems to enterprise clients, not just tutorials
- Every project includes clean, documented, tested code
- Docker-ready deployment so your system works anywhere
- Clear communication throughout the project
Tech stack:
LangChain, LangGraph, CrewAI, OpenAI API, Anthropic Claude, RAG, ChromaDB, FastAPI, Docker, Python, MLflow
Not sure if I can help? Send me a message describing your idea, and I will tell you honestly if it is feasible and how long it would take.

I'm an AI/ML engineer specializing in LLM applications, multi-agent systems, and production-ready AI pipelines. I build intelligent systems that work in the real world — not just prototypes. My expertise includes LangChain, LangGraph, CrewAI, RAG architectures, FastAPI, Docker, and MLOps. I've delivered production AI systems for enterprise clients in legal tech, scientific research, and others. Need an AI agent, RAG system, or end-to-end ML pipeline? I deliver clean, tested, documented code ready to deploy.
FAQ
What information do I need to provide to get started?
A description of what you want the AI system to do, which APIs or data sources it should connect to, and your preferred programming environment. The more detail you provide, the faster we can start.
Do I need an OpenAI or Anthropic API key?
Yes, you will need your own API keys for whichever LLM we use. I will guide you on how to set them up if needed.
Will I be able to modify the code after delivery?
Yes. All code is clean, well-documented, and delivered with a README explaining how everything works so you or your team can maintain and extend it.
Can you integrate the AI system with my existing software?
In most cases yes. Send me a message describing your current stack and I will confirm before you place an order.
What happens if something is not working after delivery?
I offer revisions as part of every package. If there is a bug in my code I will fix it at no extra charge within the revision period.
