Agentic RAG Chatbot System

FastAPI, Qdrant, Elasticsearch, Redis, Gemini, Groq

• Built a multilingual agentic RAG chatbot with NLP & AI, Legal Advisor, platform search, and web search modes.

• Implemented hybrid retrieval pipelines combining BGE-M3 embeddings, BM25 search, Reciprocal Rank Fusion (RRF),

reranking, and faithfulness verification.

• Added platform entity search, web fallback integration, session-aware memory, and document upload retrieval workflows.

• Achieved Precision@5 of 0.75, Recall@5 of 0.94, MRR of 0.88, and BERTScore F1 of 0.95 during evaluation experiments.

Autonomous Web Scraping Agent

Python, Celery, Redis, PostgreSQL, Gemini API, BeautifulSoup

• Built an autonomous scraping agent aggregating Arabic NLP resources from 198+ sources including datasets, tools,

courses, and research opportunities.

• Implemented prompt-based discovery allowing dynamic search and extraction from new web sources.

• Designed multi-stage pipelines for validation, LLM extraction, semantic deduplication, quality scoring, and asynchronous

processing.
