About Tzu-Hsien (Adam) Yu
I am a Product Designer based in London, with 5+ years of experience leading end-to-end product design in B2B SaaS.
I specialise in product-led growth and AI-enabled experiences. I combine user research, behavioural analytics, functional AI prototyping, and cross-functional leadership to deliver measurable commercial outcomes—including $50K+ in MRR growth, a 67% reduction in time to activation, and a 15% increase in subscriber acquisition.
I bridge commercial product design with dedicated research in Human-AI Interaction. For my MSc dissertation at City St George’s, University of London, I built 5 functional LLM prototypes and conducted a 33-participant mixed-methods study exploring how structured UI controls help users formulate prompts, generate ideas, and retain agency in LLM-powered products.
I also build with AI-assisted development tools like Claude Code, Codex, and Antigravity, using functional prototyping to stress-test non-deterministic AI behaviours and real-time interactions that static Figma mocks cannot capture. Authorised to work in the UK.
Companies I've worked with
My professional career is summarised below:
- Vyond, Senior UX Designer (Mar 2023 - Jul 2025)
- Vyond, UX Designer (Nov 2021 - Feb 2023)
- beBit, UX Consultant (Aug 2020 - Nov 2021)
- PDIS, UX Design Intern (2019)
- Alfred Camera, UX Design Intern (2017 - 2018)
At Vyond, I led growth and monetisation work across acquisition, onboarding, subscription conversion, and AI feature scaling. Earlier, I designed enterprise collaboration and AI-enabled workflows, including video translation, folder sharing, and a shared media library.
Across my time at Vyond, I facilitated 40+ cross-functional design critiques with teams in Taiwan, Hong Kong, and Thailand, and extended the design system with reusable component states and interaction patterns.
At beBit, I delivered UX strategy and product design for mobile services across finance, insurance, and e-commerce. This included leading the design work for 7-Eleven Taiwan’s OPENPOINT super app.
Education
I hold several degrees, including:
MSc User Experience Engineering— City St George’s, University of London (Sep 2025 - Oct 2026, expected)
- CIEHF-accredited technical MSc focused on the fit between people and technology.
- Dissertation: Designing faceted interfaces for generative AI tools.
- Modules include AI for UX Professionals, Experiencing AI, Low Code for UX, Human Factors, Inclusive Design, Virtual Reality Design and Development, and Computing the User Experience.
MBA Service Science — National Tsing Hua University (2020)
- Graduated with a dual-track certificate on service design and business analytics.
BA Library and Information Science — National Taiwan University (2018)
- Trained with information behavior, information psychology, information architecture, and human-computer interaction theories.
How I work
- I treat rejected designs as valuable signals — in the Vyond AI Credits project, I actively argued against a dark-pattern upsell approach to protect user trust.
- I don't wait for data to be handed to me — I run my own Amplitude queries to identify drop-off points and build design hypotheses before proposing solutions.
- I focus on measurable outcomes — every design decision I make is tied to a business or user metric, from MRR growth to task completion rates.
