About Tongye Liu
I design complex workflows and the systems that help teams keep using them.
My work sits where business rules, permissions, financial logic and daily user behaviour meet.
I'm a product designer in London and the sole designer for Proteus, an enterprise B2B SaaS platform at Xergy Group. I own product design from discovery through delivery, often turning loose operational rules into structures the team can actually build on.

Designer on the product, with no dedicated PM
How I Work
I treat workflows as systems, not isolated screens.
01 System
Understand the operating logic first
I start by piecing together how the work really happens: user research, existing workflows, edge cases and conversations with the CTO, BA and product team. Most projects come with business and technical constraints, so I clarify the logic before designing a flow that still feels smooth, realistic and buildable.
02 Product
Challenge the brief until the flow makes sense
With no dedicated PM on the team, I often help shape the product around the design. That means asking questions, pushing back on gaps and working through trade-offs with the BA, customers, front end engineers and the wider product team before the flow settles.
03 Handover
Make the flow easy to understand and update
I build master components, flows and prototypes in Figma so developers can follow the whole experience, not just inspect isolated screens. When new requirements come in, the file structure lets me update patterns quickly, while design system maintenance and organised files also support marketing and sales when they need design work for pitching.
Recently
AI now supports each part of how I work.
I use AI as a thinking partner across the same three moves: understanding messy requirements, challenging flow decisions and preparing clearer handover material. It helps me structure information, quickly sketch wireframes to support discussion and early validation, compare wording options and pressure test rationale before the design moves into the file. The judgement stays mine.
