BILLIE ZHANG / 张贝
Experiences people want to use
My design principle is that what makes people want to use a product matters more than its feature set.
Trained in industrial design, I led product and service design at Tencent Cloud CODING and have applied this principle across fintech, brand IP and design engineering at TDesign.
Design leadership in practice
Product insight and strategy
Find a product opportunity in everyday tasks and make the key Buddio decisions tangible in a working prototype.

See the case →Design systems and engineering
Make tools, standards and deliverables discoverable through the D2C site and AIStudio.
See the case →Collaboration and delivery
Work across pre-sales, product and engineering at CODING, and organize expert participation in Hunyuan and evaluation work.

01 / PRODUCT DIRECTION & PROTOTYPING
Buddio
How can a personal agent carry a task forward and return the decision when a trade-off needs judgment?
- My contribution
- I organized everyday needs around modes and made tasks, approvals and artifacts things a person can return to. Buddio is a working sample of those product decisions.
- Delivery and evidence
- The rule-driven demo shows task state, approvals and artifacts. The cloud demo restores state and reconciles progress when revisited.

02 / DESIGN ENGINEERING & ADOPTION
Tencent D2C website
Make a design-to-code tool easier to understand, try and share.
- My contribution
- I improved navigation, entry points and interaction styles on the homepage and mobile Insight page, and updated the WeCom share image and metadata.
- Delivery and evidence
- The authored commits are in the mainline. The site, Insight report and launch materials are team deliverables.
03 / TOOL DISCOVERY & ARTIFACTS
TDesign AIStudio
Give users one place to discover tools and examples and see what Design to HTML produces.
- My contribution
- I contributed to the site redesign, connected the homepage card to the detail page and integrated a side-by-side design and semantic HTML example.
- Delivery and evidence
- The authored commits cover the site redesign and landing-page integration. The page demonstrates an output from the team’s preprocessing workflow.
04 / BRAND & FINANCIAL SERVICES
Fusion Bank
Carry a digital bank’s brand promise into key moments such as onboarding, funding and transfers.
- My contribution
- In a marketing and design role, I worked across experience design, user research, brand and marketing for the app and wallet integration.
- Delivery and evidence
- The team’s service blueprint connects the brand, personas and service touchpoints. The bank publishes its current personal account opening process.
See Fusion Bank’s account opening guide ↗05 / ENTERPRISE EXPERIENCE & COLLABORATION
Tencent Cloud CODING / Cloud Studio
Understand developer productivity from both everyday use and enterprise pre-sales.
- My contribution
- As Product and Service Design Director, I contributed to DevOps service standards and the Cloud Studio experience architecture. I joined a pre-sales customer visit, recorded observations and proposed improvements.
- Delivery and evidence
- Project materials document the team’s workspace and community-content design and observations from the customer visit.
Additional work and publications

Tencent Hunyuan / Diorama Town
I organized Tencent frontend and design experts to support model training and fine-tuning. Diorama Town is a team showcase.

3T / Evidence for design judgment
I co-developed the design intent workflow, experience mechanisms and expert collaboration. Offline attribution is a prototype, with expert agreement still being calibrated.

DesignBench / Output and process
I contributed to tasks, review mechanisms, expert collaboration and the presentation of execution traces. Formal blind review is still being calibrated.
Brand IP and commercialization
I worked as a TiMi IP deputy producer with commercialization responsibilities and led Tencent’s Fortune Goose brand. The IPENGOO catalog documents the team’s product lines and collaborations.
Co-translator of the Chinese edition of A Project Guide to UX Design. In “From Impression to Phenomenon,” I shared how brand perception relates to the experience people have over time.
