Backend developer since 2005. Primarily Python/Django, lots of experience in adjacent areas. I had many responsibilities since I started professional work in the IT industry in 2005. Some projects I built by myself from the ground up, to create others I led a team. These days I tend to work independently on website backends, primarily in Python/Django.
