Dual practice

Systems with logic. Motion with feeling.

Product systems + prototype lab

Seven years translating payment, eGift, eSIM, portal, identity, and multi-market rules into buildable experiences and implementation-ready prototypes.

3D animation

A foundation in modeling, camera, animation timing, and visual storytelling. I bring that spatial instinct into product motion and interactive presentation.

3D / Motion archive

Spatial thinking, frame by frame.

My 3D background is not a decorative side note. It shapes how I see depth, hierarchy, camera, state change, rhythm, and the emotional timing of an interface.
