PROFILE

Pavel Porvatov

Worked on UI modernization, performance optimization, and maintainability improvements across JetBrains/intellij-community and JetBrains/resharper-unity repositories. Focused on refactoring legacy Java Swing components to Kotlin UI DSL, enhancing accessibility, and reducing UI freezes when handling large datasets. Migrated key UI panels, improved tooltip handling, and introduced caching mechanisms to streamline user interactions and lower null-safety risks. Updated Subversion and VCS settings interfaces for better usability and migrated VCS UI logic to Kotlin for future maintainability. In JetBrains/resharper-unity, replaced deprecated UI APIs and simplified dialog components, aligning with design standards and reducing technical debt. Utilized Java, Kotlin, and Swing.
