I will build a reliable ai agent, llm integration or rag system

I take AI features from demo to production in TypeScript/Node or Python: an LLM integration, a RAG system over your documents, or an agent that calls your tools reliably. Every order comes with checks that tell you it works.

Receipts: I built a multi-provider LLM gateway, wire-compatible with OpenAI, Anthropic and Gemini, that runs in production across 5 products. I've shipped RAG over internal data to production, and on one platform raised retrieval on a fixed 12-question benchmark from 1/12 to 8/12 answered. I ran an open-weight model pipeline for a data-labelling platform with 500K+ users.

How it works: every order starts with a short written spec and acceptance tests we agree on. I build against them and deliver the code, a short write-up and an eval set with a control that must fail, so you can rerun the check instead of taking it on trust.

Good fits: a chatbot or RAG system that gives wrong answers, an agent that needs to call your tools reliably, or a move to a cheaper model without losing quality. Message me a few lines on what you're building before you order.
