Participated in the development of plugins for Jira and Confluence to implement the law on personal data of European Union citizens.- Limited access for unregistered users and users without proper access rights to prevent information leakage and application hacking, and also reduced the likelihood of dormant XSS vulnerabilities following the work of a security specialist;- Improved code readability by refactoring applications creating a single multi-module project with the allocation of a common part for Jira and Confluence plugins;- Improved interaction with users by introducing support for variables for sending messages to email, which made the notification about found and made confidential information more visible and convenient;- Reduced the time that developers spend on bug fixing by increasing code coverage with tests from 15 to 64 percent, which also significantly accelerated and simplified the introduction of new functionality;- Reduced the time of the code-review process by creating documentation and a todo-list for creating a pull-request, and now developers do not spend time writing comments on frequently repeated errors;- Reduced the application’s operating time with an identical volume of data by 2.5 times through the optimization of queries to Atlassian’s native databases;- Improved application capabilities by expanding the functionality of processed data - provided the ability to search for anonymous information in attached to Issue files of .xls, .xlsx, .doc, .docx, .pdf formats.

Participated in the development of a Confluence plugin for sending pages via email. One of the most important and significant tasks on the project was the introduction of a feature to send all pages from certain sections for the past period according to a schedule. I thought through the variability of setting up this scheduler for sending by time, days of the week, dates, specific days of each month, and released it using Spring Scheduler. In the future, this functionality was included in the general version of the plugin, as it was in demand by many customers.
