Open to remote opportunities

I teach, design, and build software.

Background
I’m Lim Houy Hyong, based in Phnom Penh, Cambodia. I studied Computer Science and English side by side, trained in software development, and earned a Master’s degree in IT & Engineering, with research focused on deep learning.
What I do
Today, I’m an IT Instructor at Korea Software HRD Center and work on software projects, bringing together my interests in user experience, design, and technology.
What drives me
I enjoy understanding people’s needs, simplifying complex problems, and turning ideas into useful digital experiences. I’m always exploring new ways to learn, create, and bring ideas to life.

Three tracks, rarely one at a time

Most years I’ve been studying, teaching, and building at once. Each one feeds the others: teaching shows me where people get stuck, and building tests whether I’ve really understood what I studied.

How I approach projects

Start with people
I take time to understand users, their needs, and the problems a product should solve before deciding what to build.
Connect design and development
I work across Figma and Next.js, helping ideas move from initial concepts to functional digital products.
Keep things clear
Teaching and working across four languages have shaped how I communicate, explain ideas, and design experiences for different people.

I work in four languages

I’ve taught Khmer to Chinese speakers and Chinese to Khmer students. Moving between languages showed me how much meaning gets lost between people, and how much clear design and writing can save.
