Veelgestelde vragen
Do you provide deployment or hosting service?
No. I only deliver complete source‑code. Deployment, server hosting and online maintenance are the client’s own responsibility. I will not handle any deployment‑related work.
Which vector database will you use for my project?
Depends on your project scale. Chroma for small prototypes; Qdrant / PostgreSQL‑pgvector / Pinecone for production‑ready projects. We will confirm details before you place the order.
Do I need to provide my own LLM API keys?
Yes. You need to prepare your own API keys for your target LLM (OpenAI / Claude / Gemini / Ollama etc). I do not supply API‑keys.
Can you modify or extend my existing RAG / LangGraph project?
Absolutely. Please send me your existing source‑code and requirements via message before ordering. I will assess whether I can work on it.
What information do I need to prepare before ordering?
Please prepare: business scenario description, target LLM, document types for RAG, and agent tool/logic requirements. Message me first to discuss your project.
