Welcome to Bk42!

Hello, my name Guilherme Myr and I am the founder of BK42 Design.

I enjoy turning complex problems into simple, beautiful and intuitive designs. When I’m not pushing pixels, you’ll find me building and riding out my custom bike.

I specialize in User Interface design, branding, web design, and offer design services to businesses of all sizes around the world, ultimately improving their bottom line by crafting creative solutions to their business and identity problems.

I have been in the industry for the past 15+ years, I have worked with many professionals throughout my career so far, I have worked for brands like BMW, Microsoft, Citi Bank, Apple, and many more.

My clients are always my first priority.
I’m very happy to see you here!
