Lyah Ed Tech

Built a full-stack AI tutor/copilot assistant: a conversational agent with intent classification and document-grounded retrieval (RAG), surfaced through a real-time WebSocket chat with persistence, inline editing/feedback, and export-to-Word.
Developed an LLM evaluation and automated prompt-optimization pipeline (LiteLLM + Opik MetaPrompt), reaching 96.3% decision accuracy with precision/recall/F1 metrics and production drift monitoring.
