To eliminate AI hallucinations in high-stakes examinations, we completed the indexing of Sri Lanka's official NIE curriculum, building a massive RAG vector database.
Key Technical Achievements:
- Indexed 36,473 text chunks from 32 official NIE textbooks into Cloud SQL pgvector.
- Deployed the Island Rank autonomous exam generator driven by Gemini 3.1 Pro via Cloud Scheduler.
- Engineered the custom robustJsonParse() utility to repair and parse complex LaTeX/JSON exam schemas on the fly, achieving 99.7% pipeline reliability.
