Hello, I'm Yu Hang, though most people know me as Mervin. I'm an 18-year-old student at Singapore Polytechnic, pursuing a Diploma in Applied AI & Analytics. From a young age, I've been fascinated by computers and technology, and this passion has grown into a strong interest in building AI tools and full-stack applications with AI integration. My goal is to one day create a groundbreaking application that impacts millions of people worldwide.
A full-stack FastAPI application that transforms PDFs/DOCX into structured mock exam papers and answer keys. Integrates OCR + NLP (LLMs) for text extraction and question generation, and uses ReportLab for professional PDF formatting with math rendering, tables, and MCQs. Designed to help students and educators generate practice materials quickly and consistently.
