Tutoring

Since many years I have been conducting private tutoring lessons in math and physics on several levels - mostly for high school and technical universities students. In the projects section below you can also find an orthodrome calculator that I have created several years ago for students of Gdynia Maritime University.

Learning

I spend as much time as possible on learning new things and improve my skills. My most important private project currently is the Squash app (see below) which helps me to improve my skills in the field of Angular, Java, Spring Boot (including Spring Data, JPA and Security), as well as databases and UX design.

Activities

As soon as I'm done with all the stuff mentioned above I'm taking care of several sports activities: mostly squash playing and bicycling (rather as an amateur). I'm also a honored blood donor, awarded with the Polish Red Cross badge of the highest level.
