About me

Sebastian Płoszaj
PHP Developer

Creating websites has already become a path for me to use my creativity in high school. I was very passionate about the eHogwart browser game I designed. After graduating from high school, I chose development my humanistic interests - history, philosophy and psychology, where I could use my ability to think analytically also. In private, my hobbies are music and sports.
