Portrait of brand designer Kai Marlow

I don’t start by jumping straight into the code. I start by understanding what you’re trying to build and what you actually need. Whether it’s a website, an app, or something behind the scenes, I’ll help you work through the idea and find the right way to bring it to life.

Outside of work, I’m usually listening to music, working on my own ideas, or learning something new. I like building things even when there’s no client involved — sometimes just to see if an idea can work. And when I’m not behind a screen, I’m probably painting or playing with my cats.
