About

Hi, I'm Kerem.

I've been building web and mobile products since 2020. I currently work as a frontend and mobile developer at Interlink Group, and on freelance projects I take on corporate websites, admin panels and APIs end to end.

I care about clean, maintainable code and about standing behind the work I deliver. When I'm not coding, you'll most likely find me by the sea.
