Shirley Xue

Berlin · Senior Product Designer

I design products. Then I build them.

I'm a Berlin-based senior product designer who takes complex products from customer research to launch, then builds the working software to test and ship them. At ablefy I design across payments and compliance and built a production customer-insights system. 12+ years in product, including around seven years in product design.

Nobody could hear what customers were telling us

The AI system I built and run in production — taxonomy, pipeline, and a Slack agent colleagues query themselves.

A Voice-of-Customer system owned end to end — taxonomy, signal model, a multi-channel LLM pipeline with automated evals, and a Slack agent colleagues query directly: one typical week, 25 questions from 7 people, every answer graded by an automated judge. Built solo, running AI coding agents as the engineering team.

Designing where every deal is a negotiation

The product I stayed with longest at ablefy: two and a half years as its only designer, first proposal to handover.

The B2B sales product line for high-ticket sellers — deal flows, multi-role commissions, payouts, analytics. Sole designer for 2.5 years, from the first proposal to a handover that came with a queryable AI knowledge base of 29 dated artifacts. Shipped.

Payment and tax surfaces, designed and merged

Here my design lands in production as code I wrote and merged myself — payouts and tax.

Payouts, collections, seller-side tax classification, admission tax, a Pay Later method and product access settings — designed and coded in the production web client. Sole designer across the two teams that own them; open directions handed over as running branches.

A community that starts from the product you already sell

Where I designed what the AI draft does when it comes back wrong.

A community product rebuilt from scratch on a new stack. The setup flow reads the product a seller already sells and drafts the community around it — name, description, opening rooms — for them to edit and approve. Validated in a beta programme of 22 onboarding sessions before launch.

About

The designer who builds

I'm a senior product designer at ablefy in Berlin, a creator-commerce platform — sole designer for the two teams that own payments and compliance, owning customer research end to end. I started in product, as a product manager at Tencent on 100M-user products, then left Big Tech to be the founding product lead on a dive-trip booking app, shipping v1 with one engineer. Design came next, full-time in EdTech.

I take new products from zero to launch. At ablefy I brought the sales product, community product and affiliate marketplace from first problem to shipped release, and I have worked with almost every team there.

I believe design judgment sharpens when you build the thing yourself. Working in code helps me test decisions early and hand engineers something runnable. I build working prototypes against the production design system, so teams can test real flows before committing engineering time. My research claims carry counts and denominators, and my AI work ships behind evals. Most recently that meant building an AI customer-insights platform solo — seven feedback channels, an LLM pipeline, a Slack agent — by directing AI coding agents as the engineering team I didn't have.

Leading, alongside the IC work

  • Managed a user researcher and a UX writer
  • Mentored the designer who took over my sales product line
  • Wrote and ran the workshop that gets non-engineers shipping reviewed front-end changes with AI — re-run by a colleague after me
  • Started the cross-team design review at Alef; it outlived the project
  • User research & customer insights
  • Design systems & UI craft
  • Prototyping in production code
  • AI pipelines & evals

The dots, connected

Four industries, one habit: find what people need, then ship it.

  2. 2015

    Founding product lead on a dive-trip booking app — China's first dedicated diving booking platform

  5. 2023

    Senior product designer at ablefy, Berlin — new products from zero, now payments and compliance

The dive shop meant gear, courses and boat trips. Off hours it's still diving, plus climbing, dancing, painting, a corgi who supervises — and the occasional hackathon stage.

Let's work together

Based in Berlin, working in English, at home in remote teams — Alef ran fully remote, ablefy largely remote; today I work hybrid. Most useful on a problem nobody has framed yet, in a team small enough that the designer also builds — research to running software. The fastest way to reach me is email.
