Beyond Code
Things I love
🎨
Art & Illustration
@kleikei_doodlesI love creating art — from digital illustrations to hand-drawn pieces. Art keeps me thinking visually and feeds directly into how I approach UI and product design. A good eye for aesthetics makes a better developer.

Photography & Shoots
@yings.pngI enjoy photoshooting during my free time. I'm drawn to how composition, lighting, and mood can tell a story. This extends into how I think about visual hierarchy and layout in my digital work.
