AI Radar — RAG Research Assistant

RAG-bot that collects AI news from 7 sources and answers questions with links to the sources.

What is interesting technically:
— Hybrid search: BM25 + vector search Qdrant, merged through Reciprocal Rank Fusion, plus cross-encoder reranker
— RAGAS evaluation of answer quality (faithfulness, answer_relevancy)
— Auto-indexing via APScheduler every 6 hours
— Telegram bot as a thin httpx client to FastAPI

Stack: Python, FastAPI, LangChain, Qdrant, rank_bm25, sentence-transformers, aiogram, APScheduler, Docker, GitHub Actions.
