I will build custom ai rag application and llm knowledge base
Viktor M
About this gig
Is your LLM hallucinating? Does your business need an AI that actually knows your data?
Stop relying on generic AI models. I will build a secure, high-performance RAG system that connects top-tier Large Language Models (OpenAI, Claude, Llama 3) directly to your proprietary company data, PDFs, and databases.
Why work with me? I am an AI developer specializing in data automation and semantic search. I build robust architectures that prevent AI hallucinations, ensuring your chatbot or internal tool gives accurate, citation-backed answers every single time. I prioritize clean code, secure data handling, and excellent communication.
What I can build for you:
- Document Chatbots: AI that reads your PDFs, Word docs, and internal wikis
- Customer Support Agents: Bots that answer client queries using your actual support manuals
- Data Analysis Tools: Systems that can query both unstructured text and structured SQL databases
- Tech Stack: Python, LangChain, LlamaIndex, OpenAI/Anthropic APIs, Pinecone/ChromaDB/Supabase, and Streamlit/Next.js for the interface
Important: Please send me a message with a brief overview of your project and data size before placing an order so we can confirm the scope.

Languages
English, Ukrainian, Slovak
Python engineer building AI systems that run in production. RAG chatbots trained on your documents, AI agents for repetitive work, and the FastAPI backends underneath them.
I start with your problem, not the tech. If Zapier or n8n solves it in two days, I'll say so. If it needs real engineering, you get code you own, cost controls, guardrails, and documentation.
Send me the task eating the most hours in your week and I'll tell you if it's worth automating.
FAQ
What is RAG (Retrieval-Augmented Generation)?
RAG is a technique that connects a Large Language Model (like GPT) to your specific knowledge base. Instead of guessing, the AI searches your data first, then uses that information to generate a highly accurate, customized response.
Which Vector Databases do you use?
Depending on your scale, I can integrate Pinecone, Supabase, ChromaDB, or Milvus to ensure fast and accurate semantic search for your AI application.
Is my company data secure?
Absolutely. Your data remains in your control. I can build systems using secure cloud databases or even entirely local open-source LLMs (like Llama 3 via Ollama) for maximum privacy.
Can you connect the AI agent to my existing software?
Yes. I can build custom API integrations or connect the RAG system to tools like WhatsApp, Slack, or your CRM via webhooks.
