Pavlo Butynez contributed to the SpaceToStudy-BackEnd repository by developing and refining backend features focused on data integrity, access control, and migration reliability. Over two months, he implemented role-based access control for sensitive operations, such as restricting subject deletion to administrators, and enhanced security around user data and admin invitations. Using JavaScript, Node.js, and MongoDB, Pavlo designed and executed database migrations that removed obsolete fields, refactored data structures, and ensured schema consistency. His work included comprehensive integration and validation testing, which improved deployment safety and maintainability. These efforts addressed both feature development and critical bug fixes with technical depth.
