Hi, I'm Ronald.
I'm a product engineer, building web products on the internet, based in South Korea.
I build software that's fun to use — and still easy to change a year later. In the past I've worked with some brands you might be familiar with.

Approach
I spent years working full-time inside a large open-source codebase. A lot of my job became making it easier for the next person to work in — better tests, clearer patterns, fewer footguns. That's the part most AI-first builders skip, and it's where I spend most of my attention.
I move fast with modern tooling, but I care about what the code looks like as you expand your product. Shipping a feature is the easy part. Shipping it into a codebase that's still fun to work in next year — that's the work.
Now booking — Q3 availability
I help teams turn ideas into production software — and make existing software do more.
I embed with your team, ship code from week one, and stay until it's running in production. No drawn-out discovery phases or handoff docs — I pick up the work and collaborate with your team to get it over the line.
Most of what I take on moves from idea to live in a matter of weeks. I use modern AI tooling to move quickly without cutting corners, and leave behind code your team and agents can read, maintain, and build on.
My hours line up nicely with teams across Asia, Australia, New Zealand, and the US West Coast — but for the right team and project, I'm always happy to make it work.
Just need help with a Ghost blog? I run PixelGlass for that — custom themes, integrations, and ongoing support for Ghost publishers, without the full retainer.
