Designed and built an LLM-powered exam generation engine (Gemini and Groq) that converts uploaded textbooks into curriculum-aligned quizzes across multiple question types (MCQ, True/False, Fill-in-the-Blank, Match Pairs, Ordering) in Amharic and English. Implemented a RAG pipeline: preprocessing of PDFs/EPUBs with OCR (Tesseract with Amharic language pack), chapter boundary detection, semantic chunking (500–1000 tokens), embedding generation, and storage in Pinecone/pgvector for semantic retrieval. Built multi-layer quality assurance for relevance, duplicate detection, Bloom’s Taxonomy difficulty alignment, distractor validity checks, and a teacher review queue for low-confidence outputs. Developed an AI student performance module to identify weak chapters using per-student quiz history and surface personalized study recommendations. Architected the AI Engine as an independent Python/FastAPI microservice using async message-queue processing for textbook jobs and REST for real-time
