Shirley Xue

Berlin · Senior Product Designer

I design products. Then I build them.

I started as a product manager at Tencent, turned to design, and eventually learned to build the products myself. 12+ years across four industries; at ablefy I take products from research to launch.

Nobody could hear what customers were telling us

The AI system I built that runs in production — taxonomy, pipeline, and a Slack agent stakeholders 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 stakeholders query directly. Built solo, running AI coding agents as the engineering team.

Designing where every deal is a negotiation

The one I stayed with longest: two and a half years as its only designer, first survey 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 first survey to a structured handover. Shipped.

Payment and tax surfaces, designed and merged

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

Payouts, collections, seller-side tax classification, admission tax, a Pay Later method and product access settings — designed and merged into 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

MVP and MLP inside three months — and where I designed what the generated 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 with twelve beta sessions before launch.

Every number from the engine, not the model

A pricing form that advises, then you edit

Pricing, VAT and payment methods in one form — answered in working code, with evals, before anyone had to commit to it.

The form where sellers set every price: reordered first, then — when a regulation retired one plan type — rebuilt around two questions a seller can answer, with an AI advisor whose every number comes from a deterministic engine. Prototypes and a test instrument, not in production.

Marketplace mechanics, decided in the open

Both sides of a marketplace, 0→1 in six months — and it stayed a niche channel, which we knew early because the metrics came first.

An open affiliate marketplace inside the platform: commission and attribution mechanics argued case by case, metrics defined before launch, 30 testers before ship. Live since 2024.

The AI suggests. You decide.

A working console for an AI-operated platform

A vision demo by design — this is where I think the product goes next, built as running software you can click through.

What the platform looks like when AI does the operating: visible money spine, identity checks (KYC) as a conversation, a co-pilot that proposes and never acts alone. Vision demo, synthetic data.

About

The designer who builds

I started in product — a product manager at Tencent on 100M-user products — then left Big Tech for the diving business: founding product lead on a booking app, later co-running a dive shop with a 5,000-member community. Design came next, full-time in EdTech, and I'm now senior product designer at ablefy in Berlin — sole designer for the payments and compliance teams, owning customer research end to end.

Mostly I have been the designer who starts things. The sales product, the community product and the affiliate marketplace were each a new product I took from nothing to shipped, and each one I handed to another designer when it stabilised. I have never sat on one fixed team for long — at ablefy I have worked with almost all of them.

I believe design judgment sharpens when you build the thing yourself. I don't replace engineering — I shorten the distance between an idea and the evidence for it. My prototypes run in production code on the design system and get WCAG-AA contrast passes; my research claims carry counts and denominators; 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.

I've also managed a user researcher and a UX writer, mentored the designer who took over my sales product line, and run internal workshops that get non-engineers shipping reviewed front-end changes with AI.

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.
