HEAD OF PRODUCT (FOUNDING TEAM) @ MML ONE · VANCOUVER · CREATING SINCE 2021
Hey!
I’m Xinpeng Liu — a UX designer who also writes code, based in Vancouver. Right now I lead product on the founding team at Multimodal Media Lab, taking MML ONE, an AI film production platform, from zero to one.
The last five years span Unity Technologies, VR interaction research at SFU, and two Vancouver startups. At Zixel I was the UX designer on a new kind of CAD tool — what Figma is to Photoshop, but for CAD — and cut expert task time by 57.6%.
Today that all feeds into MML ONE: I own product, design, engineering and operations end to end, and the public alpha has grown to 2,423+ creators.

From user interview to shipped build — I design complex tools and write the code, so nothing gets lost in a handoff.

Notes
AI tools
The slot machine problem in AI tools
You get something you love, touch one thing, and it's gone. Why generation loops throw away good work.
Expert tools
If your tool needs a manual, that was a decision
Engineers don't fear complexity — they fear not knowing what the software just did.
Process
Operations is design work
Invites, release notes, feedback triage — the calendar says it isn't design. It decides what the product becomes.
Research
Precision is a budget
Zoom, snap, gain, nudge — every tool decides where your precision goes. Most never write it down.
Workflow
Why I don't hand off my designs — the same hands hear the interview, draw the screen, ship the code.
