    In 2020, after obtaining the Pole's Card, I moved from Russia to Poland, where I obtained a permanent residence permit. I didn't see any prospects for myself in my hometown of Murmansk, so I decided to learn the Polish language and make a radical change in my life by moving to Poland. While working at the library in Murmansk, I came across a Python programming language textbook. The book captivated me, and I wrote several simple programs in Python based on it. This textbook helped me realize that I wanted to study programming in Poland, and I chose the "Applied Informatics" direction at Nicolaus Copernicus University in Toruń. There, I had the additional opportunity to meet students from different countries and improve my Polish and English language skills. Reflecting on my childhood and youth, I realized that I had constantly been exposed to programming languages. In school, I studied Basic and QBasic, undertook a project to create my website using HTML and CSS, and
