About
[03+ years]

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.

01

Understand first

Interviews, scope framing, define what we're actually solving — not what we assumed going in.

02

Structure before pixels

Flows and IA locked down before anything looks pretty.

03

Build the system, not just the screen

Components and tokens that hold up when the product grows.

04

Ship with edge cases covered

Loading, empty, error — not just the happy path.

Client testimonial

Hy bridges design and execution. We moved from scattered ideas to shippable product decisions much faster than expected.
