About.txt
Hi, I'm Mandy.
I'm a product designer based in Tokyo, designing for the past 8 years in various industries such as social media, travel, and B2B SaaS. I love working with people and am collaborative by nature. I'm known for building high-fidelity prototypes to align teams and communicate vision. One of them was featured in Times Square.
Outside of work, I enjoy traveling (20 countries visited and counting!), watching anime, doing yoga, playing games, and adding to my Chiikawa collection.
I'm open to product design roles with teams that lead with empathy and a passion for their users (while having fun too). If that sounds like a match, let's chat!
