About this gig

Need your team to instantly find answers from your documents, manuals, or internal knowledge without digging through folders? I'll build you a private AI knowledge base using RAG (Retrieval-Augmented Generation).


 What you get:

 - Upload your documents (PDF, Word, TXT, web pages) AI understands them

 - Ask questions in plain English Get accurate answers with source references

 - Vector database backend (Qdrant) for fast, semantic search

 - Fully private runs on your own server, your data never leaves

 - Docker deployment one command to start


 Tech stack: Java (Spring Boot), Qdrant vector database, OpenAI API, Docker


 I built Progress-AI from scratch a full AI-driven project management platform with 50+ API controllers and a complete RAG pipeline. Your project benefits from that real-world experience.

I build backend systems and AI integrations — not just CRUD. Java (Spring Boot), React/Vue (TypeScript), Docker, MySQL, Redis, and AI/LLM integration (OpenAI, vector databases, RAG). I created Progress-AI (progressai.dev), an open-source AI-driven project management platform with 50+ API controllers and a full AI pipeline. When you hire me, you get someone who can see the whole picture. Clear communication, on-time delivery, code that works.
