Gayanuka's Space

Hi, I’m Gayanuka.
I build systems
that see &,
sometimes ones
that read back.

Electrical Engineering graduate at the University of Moratuwa.
My work focuses on Computer Vision, Edge AI and Multimodal Learning, with a passion for research and application development.

Beyond projects, I write the occasional blog, take photos, and play a few games.
