Petar Perovic portrait

Hello. I’m Petar Perović. I run product design and help with strategy at Semaphore, a tool for developers.

My expertise is in design and production of software that is useful, accessible, ethical and meaningful.


This website doesn’t track or collect any data. It’s running on Jekyll with Tachyons. It’s hosted on GitHub, and Netlify helps with deployment. Type is set in Fira Sans.


Reflections about design, software, how systems relate to each other and how they impact the society.
