Hazuki Yamanaka | UX Designer / Product Designer

👋 Hi! I'm Hazuki, a product designer with 6+ years of digital customer support experience!

My background in customer support taught me to empathize, identify, and validate real user pain points. so I design with both expertise and genuine care. After years of helping customers navigate user experiences, I decided to move from defining problems to solving them!

That’s what inspired my career shift to UX!: creating experiences that are clear, intuitive, and truly helpful, while ensuring businesses and customers both benefit and grow.

About me

From Support Desk to Design Studio My journey began at a customer support desk, where I spent my days helping people navigate technology challenges. Those conversations taught me something valuable: behind every frustrated click or confused scroll is a person just trying to accomplish something important to them. That insight shapes everything I do now. The empathy I developed listening to hundreds of users directly influences how I approach design problems today. I'm grateful for that foundation—it's helped me create interfaces that feel more human and considerate.
How I Work I tend to approach projects with equal parts thoughtfulness and dedication. You'll usually find me listening carefully in meetings, organizing notes to make sure nothing falls through the cracks, and checking in with teammates to see how they're doing. I believe good design comes from understanding people first, then solving problems together. While I take my work seriously, I don't take myself too seriously—I've found that a genuine smile and willingness to help goes a long way in building trust with both users and colleagues.
Life Beyond Screens Outside of work, I find joy in simple pleasures—trying new recipes inspired by my travels, exploring local food scenes, and finding cozy cafés with good coffee. I'm always planning my next adventure. These experiences refresh my perspective and remind me of the diverse ways people interact with the world—insights I bring back to my design work.
