I was designing professional software for the space industry at the Research & Engineering Center of Saint-Petersburg Electro-Technical University. I worked on the software for telemetry analysis, project management, remote control, and data management. All the projects are under NDA, but you can learn about the problems I solved on the official website. Please, consider that projects presented on the website were made many years ago and didn't have any designers at all.
I worked on interaction logic and data behind. In the article about degree input design, I describe a small case study from my work experience. In another article about design specifications, I share my approach to it that I was implementing during my work at the research center.
