FAQ
What types of AI applications can you build?
I build RAG chatbots, AI knowledge bases, internal assistants, multi-agent systems, AI dashboards, and custom LLM-powered web applications.
Which AI models can you integrate?
I can integrate OpenAI, Claude, Gemini, Mistral, Llama, and other commercial or open-weight models based on your requirements.
What is a RAG system?
RAG connects an AI model to your documents, databases, or business knowledge so its answers are grounded in relevant information.
Can the AI cite its sources?
Yes. The application can display document names, links, passages, or references used to generate each answer.
Can you connect the system to my private data?
Yes. I can connect PDFs, websites, databases, spreadsheets, cloud storage, APIs, and other approved data sources.
Can the AI application run locally?
Yes, when your infrastructure supports the selected model and expected workload. I can also design private cloud or hybrid deployments.
Will the AI always provide accurate answers?
No AI system can guarantee perfect accuracy. I improve reliability through retrieval, validation, guardrails, evaluations, and source citations.
Do I receive the source code?
Yes. You receive the custom source code, repository, and agreed documentation upon successful project completion.
Can you improve an existing AI application?
Yes. I can audit, repair, extend, or redesign an existing AI application, RAG pipeline, agent workflow, or prototype.
Can I see a demo before ordering?
Yes. Message me with your use case, and I can produce a free tailored project demo in under 24 hours.
