Dacheng Chang

Senior UX designer for AI, B2B SaaS & ecommerce

Design systems, branding, marketing, and CRO — from product craft to conversion.

About

Product craft that carries through to conversion

I’m a senior UX designer who owns the experience end to end. Complex B2B tools, ecommerce journeys, and marketing surfaces that have to convert. I’ve shipped work on AI-powered products and I use AI to push research and design exploration further.

I partner with founders, PMs, engineers and lead with clarity, then craft, ship, and reflect.

Focus

Where I create the most leverage

  • AI product UX

    Prompting, grounding, feedback loops, and trust patterns that make model behavior understandable.

  • Interaction systems

    Reusable patterns, states, and motion that keep complex products coherent as they scale.

  • 0→1 product design

    From fuzzy opportunity to crisp MVP: information architecture, flows, and visual direction.

Approach

Clarity first. Then craft.

Start with the decision

Every screen should help someone decide or act. I reverse-engineer the experience from the outcome.

Make the system legible

AI feels magical until it fails. I design for uncertainty, recovery, and progressive disclosure.

Ship with taste

Modern doesn’t mean loud. I aim for interfaces that feel precise, calm, and quietly distinctive.

AI harness

Prototyping faster with modern AI tooling

My AI harness covers research, design, and development — then I refine with craft, critique, and judgment.

Design leadership

Building teams that ship with clarity

I lead design practice with the same rigor I bring to product craft — direction, mentorship, and measurable outcomes.

  • Team management

    Managed 2 graphic designers and 2 UX designers, leading sprint planning, design critiques, and career progression frameworks.

  • Mentorship & quality

    Mentored junior designers in design-system contribution, stakeholder presentation, and user-research rigor.
