its place

simplicity is
the hardest part
I don't just push pixels, I solve problems with code and craft. Every project is a chance to make something someone genuinely enjoys using.

- About Me
I sit at the intersection of design and engineering and I refuse to pick just one.
I'm Piumal Dhanawardhana, a product designer and full stack developer from Colombo, Sri Lanka. I started by breaking things apart to see how they worked - turns out, that's still how I approach every project.
My toolkit spans TypeScript, React, Next.js, and Astro on the web, with Swift and React Native for mobile. But tools are secondary - what matters is whether the thing I build actually solves a problem without making the user think twice.
When I'm not designing or coding, I'm probably sketching UI ideas in a notebook, reading about design history, or debugging something that worked perfectly five minutes ago.
