Hey I'm Marica
I'm a Berlin based software developer with over 5 years of experience building delightful web experiences

I like building clean, intuitive web interfaces that make whitespace look good. I also enjoy simplifying complexities and getting things deeply fixed.
When I'm not working: I'm an amateur designer, bathroom singer and an absolute glut.
