Had several long-term projects from regular customers.I have a higher education, graduated with a master's degree in System Programming in 2001. I have more than 7 years of experience working with Python.I have experience working with multi-threading, experience designing systems, writing desktop applications using the QT library, writing parsers using the Scrapy framework, t ried using FastAPI, Flask and so on.Before Python became the main programming language, I developed in C++ (a long but long time ago). Recently, for about a year, in addition to Django, I've been doing full-stack development using React - I've learned JavaScript and TypeScript, CSS layout and front-end development.I have experience working with the necessary tools for developing testing and deploying projects.I take my work as seriously as possible and try to perform it as well as possible.My father used to tell me: "Try to do well, bad things will turn out by themselves." :) I always try to do just that.I have experience working in a team and managing a team.
