The system combines RAG-based job chatbot, text-to-SQL smart search, CV analysis with LLM-driven career path recommendations and skill gap analysis, mock interview simulation, and a market demand dashboard. The post covers the full development pipeline: data exploration and cleaning with pandas, salary prediction using Ridge/RandomForest/GradientBoosting regression models, data ingestion into SQL and Qdrant vector database, and a Streamlit frontend connected to an n8n workflow backend. Key design choices include privacy-first CV handling (no storage after processing), cosine similarity for semantic search, and self-hosted n8n for data privacy. ## Full article daily.dev links to this article rather than hosting it.
