Understand the product and constraints
Most outsourced projects start with incomplete context. I spend time clarifying users, workflows, edge cases, and technical limits before pushing pixels
I started with design. Then I learned to build the system.
Khang Hy · Product designer and Builder. Based in Ho Chi Minh City.
I work best inside real constraints. NDA from a Japanese client. No direct user access. A 60-hour deadline. Three-year-old specs nobody had read all the way through. Those projects aren't ideal — but that's when I do my best work.
Experience
Where I've worked
01
HMI for a semiconductor wafer grinder
Japanese client · NDA
Zero-error environment, strict NDA, 3 vendors, one coherent interface.
02
FeedbackMe
Internal tool → B2B SaaS
12 months. Every new client used to need a developer to configure manually. The rebuild changed that.
03
Construction Tech Platform
Japanese market · multi-party system
Five roles. One data backbone. A multi-party construction platform built for the Japanese market.
04
Btaxi
Cambodian market · rider / driver / admin
3 apps. Dual role as designer and product lead. Khmer script, QR payments, and low-end Android constraints all shaped the product.
05
DStore
Solo build · e-commerce
60 hours from logo to storefront, admin, and payment integration.
Case studies show how research, systems thinking, and shippable interfaces come together — from HMI operator tools to full mobile ecosystems.

Execution Advantage
How a project actually runs with me.
02
Structure first
I focus on flow, hierarchy, and reusable patterns before polishing screens. That usually leads to better decisions later in design and development.
03
Design for delivery
I try to leave behind files that developers can actually work with — not just nice screenshots. That means thinking about states, consistency, and handoff early.
04
Stay practical
I’m less interested in making things look “premium” for one presentation, and more interested in making the product clearer, more usable, and easier to ship.
Client testimonial
Hy bridges design and execution. We moved from scattered ideas to shippable product decisions much faster than expected.
