About
I am currently studying Computer Science at The Chinese University of Hong Kong (CUHK), with proficiency in C#, Java, Python, React, and R. I have developed a diverse skill set that combines core programming with data analysis and multimedia content creation.
Previously, as an Innovation Project Developer, I engineered a solution using brainwave technology to detect driver sleepiness, demonstrating my ability to apply technical skills to solve real-world problems. This project won the Gold Award at ICAN 2021 and the 21st Hong Kong Youth Science & Technology Innovation Competition.
My experience spans from AI solutions development and Android applications to community leadership through the CUHK Lead Programme. I'm passionate about leveraging technology to create meaningful impact while continuously expanding my expertise in cybersecurity, cloud computing, and software engineering.
