(ABOUT ME)

I am Sum, meaning 'heart' in Chinese.

As a product designer with a unique background in law enforcement and financial crime compliance, I bring a diverse skill set to the tech industry. My experience spans digital professional coaching, automotive design, and contract management, with a focus on complex UX projects.


My journey began as a detective in Hong Kong, where I progressed from a Sub-unit Commander to roles at divisional, district, and Headquarter levels. This experience sharpened my problem-solving skills, resilience, and leadership abilities, which I now apply to my work in tech.

After relocating to Germany and working in financial crime compliance, I transitioned to tech and product design. I have since collaborated with early-stage startups and an agency specializing in automotive design, contributing to UX projects for Volkswagen commercial vehicles.

I do my best work remotely when I need deep focus, but I genuinely enjoy office time too. Coffee chats, design critiques, being around the team, and yes, killing the snacks!

Outside of work, I draw @Puiyi Comics based on my daily life, experimenting with different character styles and storytelling approaches.
