About Me

Hello! I'm Oscar, a passionate beginner in deep learning and AI development.

A technology and education professional with a strong foundation in Computer Science (BEng, HKUST) and a Master’s in Information Technology in Education (HKU). Over the past six years, I worked as an instructional designer at EdUHK, specializing in leveraging technology to craft impactful and engaging learning experiences.

As we enter the AI era, my focus has shifted toward Artificial Intelligence, particularly in areas like Natural Language Processing (NLP), Large Language Models (LLMs), and Computer Vision (CV). I’m enthusiastic about interdisciplinary collaboration, blending technical expertise with creativity to develop meaningful AI solutions across various domains. Who knows—perhaps one day, I’ll bring these innovations back to the education sector.
