Product Designer at OOZOU, Bangkok
Nabhak "Yhai" S., a designer who ships.
I sit between clients and developers. Conversations become requirements, requirements become flows, flows become a design system, and lately, working prototypes built with AI.
Before product design I made games, graphics and digital content. Games taught me that feel is a feature, not polish. Outside client work I build small tools to remove my own daily friction, then share them.
How I work, from first meeting to launch
Four steps, the same every time, so clients always know what happens next and what they get at the end of each one.
-
01
Understand
I sit in the client meetings and ask the awkward questions early. A two-hour call becomes a one-page requirement summary with scope and a timeline estimate.
You get: a one-page requirement and an estimate -
02
Structure
User flows and wireframes first, so we argue about the UX while it is still cheap to change. Competitor analysis and a workshop when the direction is fuzzy.
You get: flows and clickable wireframes -
03
Design
UI on a design system: tokens, variants and components that scale across screens and brands. Rebranding becomes a token swap, not a redo.
You get: final UI and a living design system -
04
Build
Prototypes built with AI when a click-through is not enough, then a clean handoff: named layers, one final file, tickets that match the screens.
You get: a handoff file and, sometimes, a working prototype
What I bring to a team
01UX and UI design
Flows, wireframes, final UI, prototypes. Mobile first, RTL when the market needs it.
02Design systems
Tokens, text styles, components with real variants, set up before the screens so the whole team works from one source.
03Product strategy
Requirement summaries, scope and estimates, competitor analysis, decisions written down.
04AI-powered prototyping
Working prototypes built with Claude when a click-through would hide the real question.
05Design to dev handoff
Named layers, one final file, tickets that match the screens. Developers stop asking.
06Design team mentorship
Reviews, pairing and a shared way of working so juniors ship with confidence.
07Internal tools and back-office
Dashboards and admin tools for the people who run the product, and billing portals for the admins and accountants who pay for it.
08Product review and design QA
I check the built product against the design and the user flow, then log what breaks before users find it.
09Improvement ideas for internal products
I spot where internal tools slow a team down and pitch concrete fixes, with mockups the team can react to.
