About · Nguyễn Thái Khang Hy

I started with design. Then I learned to build the system around it.

I'm a product designer and builder in Ho Chi Minh City. I take products from a rough brief to shipped: I own the design, define the product logic and business rules, and direct an AI-assisted build. I don't write the code myself. I direct the agents and developers who do, and check every screen against the rules.

Most of my work comes from outsourcing, in domains that rarely overlap: semiconductor HMI under NDA, a Japanese childcare app, a five-role construction platform, aquaculture, ride-hailing, B2B SaaS and e-commerce. Most of it shipped under tight constraints, so I validate every decision with the team, and with domain experts and the client's own team when the project allows.

Where I’m most useful

When the problem is complex, multi-role, or hard to hand off.

  • 01Rules before screensMy build has no code layer to quietly absorb a vague spec. So I write the flows, roles and business rules down first. It is the real work, not the warm-up.
  • 02Working inside real constraintsNDAs, tight budgets, markets I design for from abroad, projects joined three years in. I check every step with the engineers, and with domain experts when the project allows.
  • 03One person across the loopProduct thinking, design and build direction in one loop, so less gets lost between hand-offs.

Rules before screens.

My build has no code layer to quietly absorb a vague spec, so the spec has to be tight. That is where I spend the first days of every project.

  • Step 01Understand the product and its limitsMost briefs arrive with missing context. I map the roles, flows and edge cases, and write the business rules down before anything is drawn.
  • Step 02Structure first, polish secondFlow, hierarchy and reusable patterns come before visual detail, so the design system holds up when the product grows.
  • Step 03Direct the build, check every screenI direct the AI agents and developers who write the code, and QA each screen against the rules we agreed on. You see progress in a weekly Loom.

Getting grounded in regulated, data-heavy work

First project: an aquaculture platform. Learned to design for data-heavy field workflows fast, and redesigned a 24-screen daily entry into 7 screens.
