I can integrate OpenAI (GPT-4/GPT-5), Google Gemini, Claude, DeepSeek, Llama, Mistral, Grok, and other API-compatible or self-hosted LLMs.
Can you build AI chatbots with my own data?
Yes. I build RAG-powered AI chatbots that can answer questions using your PDFs, documents, websites, databases, or knowledge base.
What technologies do you use?
I primarily use Next.js, React, TypeScript, Vercel AI SDK, PostgreSQL (pgvector), Tailwind CSS, AWS, and modern AI frameworks.
