Image of Letty

Hi my name is Letty, even though my passport says Katja. I’m a Berlin-based software developer currently with a main focus on app development.

My background is in computer science. In the early years, I mainly developed user interfaces and thanks to my masters program went down the rabbit hole of data visualization. You may noticed in my portfolio.

In the recent years my projects where mostly web and native App projects within the web technology stack.
The term ‘Full-Stack-Developer’ probably best describes my skill set, which includes:

Nowadays I’m mostly into web development and some fun projects with SwiftUI, but my background is in Java and OpenGL.

I worked for different research institutes, agencies and NGO’s both in employee and freelance roles. As I’m happy to share my knowledge, I teach classes at different University in Germany.
