Independent Designer & Builder · 2026

Ideas deserveto become real.

I’m Twin. I turn early thoughts into clear, useful digital products—working across product thinking, interface design, and AI-assisted making.

A portfolio, made in conversation

I use Claude as a creative collaborator—not to replace the point of view, but to move faster from “what if?” to something people can see, use, and feel.

The way I work

Clear thinking. Fast making. Human taste.

  1. 01

    Clarify

    Define the real problem, the constraints, and what success looks like.

  2. 02

    Explore

    Sketch, test, and pressure ideas until the direction is clear.

  3. 03

    Build

    Ship lean, polished prototypes and working products—fast.

  4. 04

    Refine

    Learn from real use and iterate with intention and taste.

Let’s make itless hypothetical.
