View Case StudyA CSS toolkit for web devs that need to ship stunning UI fast. Animations, transitions, effects — plug and play.
View Case StudyNight skies, city streets, and everything in between — shot through glass and light.
Posters, identities, interfaces — where code meets aesthetics.
Research notes, coding discoveries, and dispatches from the observatory.
I'm Hiruja Edurapola — known as SJ. A 15-year-old builder from Sri Lanka who spends weekdays writing code, weekends stargazing, and every spare moment pushing pixels until something looks interesting.
I study at Sri Sumangala College, Panadura, and I founded Hiruja Studios and SJ Research Labs as my personal space to experiment, break things, and figure out how they work. I believe technology should be beautiful, fast, and built with curiosity.
The tools I use to turn ideas into reality.
Whether it's a collab, a project idea, or just geeking out about space — I'm down.
