About me
More than 19 years of successful development of websites, database applications, APIs development, APIs integration, desktop applications, and mobile games.

It's important to me to finish tasks in time, pay attention to the details of the task and write clear, reliable and nice-looking code. I always use best practices and test my work carefully and thoroughly. I am familiar with "code review" and "unit test coverage of a code" techniques. I have a lot of experience working with Agile methodology using JIRA, Redmine and ASANA.
