I obsess over the details
most people skip.
Product designer based in Bangkok. I work close to engineering, prototype in code, and ship instead of pitching slides.

About me

Mingalarpar, I'm Harry.
I started in computer science, writing code I was never really interested in. UX and UI was the turn — the first part of it that felt like mine. Startup competitions came next, then a first internship at Dinger that made it a career. Since then I've worked in mobile payments, enterprise SaaS, music streaming, and education.
I work close to engineering — I prototype in code and stay on a project until it's live. Off-clock, it's movies, more games than I should play, and whole weekends lost to new tools.

Have an idea in mind? A rough sketch or a half-written brief is enough to start with. We'll talk it through, and I'll take it from there.
