Casey Hou — Product Designer

Hi, I'm Casey

Product designer who thinks in systems and designs in details. Currently building fintech experiences at Ria Money Transfer.

Ria Signup Redesign

Oct 2025 – Nov 2025

I led the end-to-end redesign of Ria’s signup flow, identifying and fixing the moments that cost us conversion. I worked across engineering, PM, and QA to ship a flow that increased conversion by 10.4% and cut completion time by 17%.

Euronet Design System

Jun 2025 – Present

I unified six fragmented UI libraries into one design system, scaling decisions across teams, products, and platforms. I established design-dev feedback loop and defined clear end-to-end workflow that improved collaboration and communication, cutting delivery from months to days.

Human-AI Agent HCI Research

Oct 2024 – May 2025

I led design on a four-person research team investigating why users still felt they were doing the work when AI agents acted on their behalf. I ran co-design sessions and translated findings into a set of interaction patterns addressing the two-way communication gaps between users and agents.

Working with AI

My workflow is still evolving. New tools show up constantly, and part of my job is figuring out which ones actually make the work better :D

AI Research

I use AI to gather context fast, connecting different MCPs to surface drop-off points and behavioral patterns in the data, giving me a much clearer starting point.

AI Ideation

I start by mapping the core logic myself, then use AI to stress-test it. Through ongoing conversation with AI, I challenge my assumptions, explore variations, and work through edge cases until the flow holds up. From there, I generate a flowchart to align with stakeholders early.

AI Prototype

I build key screens in Figma, then turn them into working prototypes I can test on a real device. This allows me to quickly test ideas and validate interactions early, reducing ambiguity and enabling a smoother handoff to engineering.

AI Testing

I developed a QA system from scratch—a structured set of design rules covering layout, spacing, and component behavior, along with a checklist for review. At the end of each release cycle, I run the implementation against spec and get a clear list of what needs fixing.

Select any part of an AI response and branch off into a side conversation. A side thread opens up so you can go deeper, without losing the main conversation.

During my nearly three years at a digital agency, I worked on a range of client projects, from launched products to early-stage proposals.
