I am an AI Engineer with 3+ years of experience in NLP, Machine Learning, and LLM-powered systems. I specialize in building AI chatbots, RAG systems, knowledge assistants, and automation tools using models like GPT, BERT, and open-source LLMs.

My expertise includes prompt engineering, LLM integration, model fine-tuning, and intelligent document processing (OCR, summarization, and information extraction). I develop scalable AI solutions using Python, Flask, FastAPI, Lang Chain, and vector databases.
