About

My name is 👨🏻‍💻 Kei. I am an Experience Designer currently based in Cologne, Germany. I work predominantly for designing human-centred digital services & products, with attention to the social connections & systems behind.

In my spare time, I read about 📚📰 socio-politics, think about 🕹🔀 interactions, do 🎋✍🏼 literary explorations, 🌀👋🏼 throw pots, and take care of 🌵 plants. You can check out some of my thoughts on my public notes.

I speak English, French, Cantonese, Mandarin Chinese, and GIF; also a bit of German, Portuguese, HTML, CSS, and JavaScript. Write me via email, LinkedIn, Mastodon or Bluesky.

My background crosses design, socio-politics and digital humanities. I am an alumnus of École Normale Supérieure de Lyon, Hong Kong Baptist University and Université Sorbonne Nouvelle Paris 3.

I wrote my master’s thesis on UX of voice assistants, where I explored how to design for anticipatory assistance based on usage environments’ context. You can read it online. I also gave a guest lecture at MacEwan University’s Design Studies about UX in voice user interface (DESN 341).
