02 / The person behind the pixels

Curious by nature.
A builder by choice.

I care about what happens on the other side of the screen.

I’m a developer and entrepreneur based in Colombo, Sri Lanka. I build cross-platform applications with Flutter and React Native, work with TypeScript, Kotlin, Java, and Python, and design interfaces with Figma and Lunacy.

Alongside development, I build ventures including Yearbook Inc, Dream Technologies, and Toreno. I’m pursuing Computer Science studies and share development tutorials and insights through social media.
