What to look for in a LangChain freelancer
A strong LangChain developer should know the framework deeply and Python well. Look for:
- Current LangChain and LCEL experience, since the API moves quickly.
- A working grasp of retrieval: chunking, embeddings, and reranking that improve answers.
- Comfort with vector databases and how to keep retrieval fast and relevant.
- Debugging with traces, not guesswork, when a chain misbehaves.
- Shipped LLM apps, not only starter templates.
Ask how the candidate would reduce hallucinations and measure whether a change actually improved answers.
