Backend developer Bilimway Nov 2020 - Oct 2021 (1 year) Python backend developer The project was developed on a platform that includes a school business platform that have possible to buy a subscription. I wrote 2 versions of the platform: 1. The first was written in pure django and a little bit with the DRF library 2. The second one was also written in django, but the django-ninja-api library was used, which uses the same library as fast api At work, I did not have to use Celery, RabbitMQ, Redis, Docker. I have no commercial experience with countless technologies. Since I used a solo back-end developer, i don't have much git experience with the team. Experience with Redis and docker i have at a local deployment level.
