Image of Letty Hi my name is Letty, even though my passport says Katja. I’m a Berlin-based software developer focussing on data visualization.

My background is in computer science. In the early years, I mainly developed user interfaces, but since my masters program, I’m fascinated by data visualization.

Nowadays I’m mostly into web development, 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 the Potsdam University for Applied Science and offer workshops for groups and individuals.
