My Story
Before design, I spent seven years in the dental technology industry, from crafting dental restorations to managing digital products at Welchant and growing the Taiwan market for 3Shape. That's where I learned what makes complex technology feel simple: listening to users, explaining clearly, and caring about every detail. Today I bring that same mindset to UI/UX, motion, front-end and brand work.

My Approach

“
I learned design in a dental lab, where a tenth of a millimetre matters. Since then I've sold, trained, launched and now design, so I build interfaces that work for users, teams and the business behind them. Have a role or a project in mind? Let's talk! :)
