Design, develop, and deploy LLM-powered applications using RAG and agentic AI. Build LangChain/LangGraph agents, scalable Python ML solutions (PyTorch, TensorFlow, Hugging Face), implement vector search (FAISS, Pinecone), fine-tune and evaluate LLMs, create REST APIs (FastAPI/Flask), deploy on cloud (AWS/Azure/GCP), and apply MLOps/LLMOps, CI/CD, monitoring, and governance.
