Over deze dienst

Need a custom AI chatbot that answers using your business data instead of giving generic responses?


I will build a secure and scalable AI chatbot, RAG assistant, or LLM-powered application tailored to your use case.


With 7+ years of software engineering experience, I can deliver:


  • Custom AI chatbots and assistants
  • RAG systems for PDFs, websites, databases, and APIs
  • Python and FastAPI backends
  • LangChain and LangGraph workflows
  • OpenAI, Claude, Gemini, Llama, and other LLM integrations
  • Vector database integration and semantic search
  • React or Next.js chat interfaces
  • Authentication and role-based access
  • Third-party API and business-system integrations
  • Docker and cloud deployment


You will receive clean, maintainable source code, documentation, and clear communication throughout the project.


Every AI project has different data, security, integration, and infrastructure requirements. Message me before ordering so I can review your needs and recommend the right package.
