Über diesen Service
Struggling with a chatbot that invents answers or cannot use your business data? I build custom AI chatbots and RAG agents that answer accurately from YOUR own documents, using OpenAI, LangChain, Python and FastAPI. Custom coded, not a template or nocode bot, so you get clean code and 100 percent ownership.
What I Build:
- Custom AI chatbots trained on your data (RAG)
- Chat with your docs assistants for PDF, website and files
- AI agents with tool use and multistep reasoning
- AI SaaS platforms with multiuser access, dashboard and payments
- FastAPI backends, REST APIs, authentication and databases
Tech Stack:
- LLMs: OpenAI GPT 4o, Claude, Gemini
- Frameworks: LangChain, LlamaIndex
- Vector DBs: Pinecone, ChromaDB, FAISS
- Backend: Python, FastAPI, PostgreSQL, Redis
- Frontend and Cloud: React, Next.js, Docker, AWS
Why Me:
- 5 plus years building production AI chatbots and SaaS
- Clean, scalable code with 100 percent ownership handed over
- Deployment and after launch support included
How It Works
Scope your requirements, design the architecture, build with regular updates, then deploy and hand over.
Deploy to your website or your preferred platform.

FAQ
Can you build a complete AI SaaS product?
Yes. The Premium package is designed specifically for startups and businesses launching AI-powered SaaS applications.
What is a RAG chatbot and do I need one?
RAG (retrieval augmented generation) lets your chatbot answer from your own documents instead of guessing, so replies stay accurate and on brand. It is ideal for support bots, internal knowledge bases, and chat with your docs assistants.
Can you integrate OpenAI into my existing application?
Absolutely. I can integrate OpenAI, ChatGPT, Claude, or Gemini into existing web or mobile applications.
What data can I train the chatbot on?
Your website, PDFs, Word and text files, and other documents. In Basic I train it on 1 data source, and Standard covers a multi document knowledge base of up to 25 documents.
Do you build AI agents or only question and answer chatbots?
Both. I build simple RAG question and answer bots as well as LangChain AI agents with tool use and multistep reasoning that can call APIs and handle more complex workflows.
Do you provide source code?
Yes. All projects include complete source code ownership.
How much will the OpenAI API cost to run?
API usage is billed by OpenAI directly based on your traffic. I set up the integration efficiently and can estimate your monthly cost based on expected volume before you order.
Can you build AI chatbots using my company data?
Yes. I can create AI chatbots trained on your PDFs, website content, knowledge base, documentation, FAQs, and business data.
Can you deploy the project?
Yes. I can deploy on AWS, DigitalOcean, VPS servers, Docker environments, and cloud platforms.
