About this gig
Need an AI system that actually works end to end not just a wrapper around ChatGPT? I design and build production-ready LLM applications: multi-agent pipelines, RAG systems, autonomous agents with tool use, and AI backends that plug into your existing product. Built on LangGraph, FastAPI, and your choice of model (OpenAI, Anthropic, or open-source). Deliverable includes full source code, API documentation, and a working deployment.
I build:
- Single and multi-agent LLM pipelines (LangGraph)
- RAG systems with custom knowledge bases
- AI backends with FastAPI endpoints
- Autonomous agents with tool use and memory
Stack: Python · FastAPI · LangGraph · OpenAI / Anthropic APIs · Supabase · Redis
Every delivery includes clean source code, API documentation, and a working system. Message me with your use case before ordering I'll tell you which package fits.

FAQ
I have an idea but I'm not sure which package fits. What should I do?
Message me before ordering. Describe what you want the system to do and I'll recommend the right package or scope a custom order if your needs don't fit neatly.
Can you work with my existing codebase or do you start from scratch?
Both. If you have an existing backend or frontend I can integrate into it. Just share what you have when you message me.
Which LLM providers do you support?
OpenAI, Anthropic (Claude), and most open-source models via Ollama or Hugging Face. If you have a preference, tell me upfront.
Do you handle deployment or just hand over code?
Code delivery is included in all packages. Deployment to your infrastructure is available as a gig extra.
Will I own the source code?
Yes. Full source code is yours on delivery, no licensing strings attached.
