    I am a back end developer at Regulus Team, my technology stack is Python/Django. It’s difficult to exaggerate the meaning of the back end in software development. Every application works due to this part which is not visible to a regular user. But without the back end, nothing would work. I have learned to write code according to RESTful API standards and develop the database architecture, using the ORM arranged in Django to write complex but optimized requests. I have strong analytical and interpersonal skills; I am responsible and persistent. I love reading historical novels and going in for sports, but all my free time is dedicated to learning new technologies and gaining skills in software development
