PROFILE
Liudmila Kornilova
Liudmila Kornilova contributed to the JetBrains/intellij-community repository by delivering seven features over three months, focusing on user interface improvements, external build system integration, and performance enhancements in virtual file system (VFS) indexing. She implemented consistent project root displays and dynamic file counts in the Project View, introduced incremental indexing for dirty files, and unified progress indicators in the MacOS loader UI. Using Java, Kotlin, and Swing, Liudmila refined UI responsiveness, optimized memory management, and improved search and analysis workflows. Her work demonstrated depth in IDE development, UI/UX design, and backend indexing, resulting in a more stable and user-friendly experience.

Oct 1, 2025October 2025: Delivered MacOS loader UI refinements in JetBrains/intellij-community, focusing on user clarity and visual consistency during indexing. Implemented progress indicator color unification and clarified indexing messages by removing product-name references, aligned with platform-wide UI conventions. No major bugs fixed in this scope. The changes reduce user confusion and support inquiries, improve user trust during loading/indexing, and simplify future maintenance through consistent UI wording. Technologies/skills demonstrated include UI/UX refinement, cross-functional collaboration, and loader UI changes in a Java/Kotlin-based UI framework.

Aug 1, 2025August 2025 performance summary for JetBrains/intellij-community: - Focused delivery across three core areas: user interface improvements for project structure, integration enhancements for external build system projects, and performance/reliability improvements in VFS and indexing. These efforts collectively enhanced developer experience, reduced navigation friction, and improved project reliability in external workflows. Key features delivered include: - Project View Enhancements and VFS Directory Listing: Implemented consistent display of project roots in Project View, introduced the Count VFS File Children action, displayed file counts for VFS directories, updated the view in response to registry changes, refined file-count logic, and ensured UI refresh on first VFS load. - External Build System Project Root Integration: Added support for defining and registering a ProjectRootEntity when attaching new external build system projects, strengthening project structure handling for external integrations. - Performance and Reliability Improvements in VFS/Indexing: Implemented safe modification tracking, memory-management improvements, optimized VFS loading, and indexing reliability enhancements to reduce leaks and improve stability. Major bugs fixed and reliability improvements: - Corrected VFS file counting: do not include containing directory, and refresh UI after first VFS load to reflect changes promptly. - Removed obsolete RA usage and guarded storage access in indexing-related services to prevent project leaks in tests. - Excluded ignored files (e.g., .git) from VFS traversal to avoid unnecessary processing and memory use. - Expanded indexing to cover non-indexable content, ensuring comprehensive content iteration for search/indexing. - Documentation and logging improvements: guidance to use WorkspaceModel.eventLog for event logging in long-running processes. Overall impact and accomplishments: - Improved developer experience through accurate, responsive Project View and reliable VFS interactions. - Strengthened integration with external build systems via ProjectRootEntity, enabling smoother onboarding and consistency for external projects. - Increased stability and performance of the VFS and indexing subsystems, reducing memory footprint and preventing regressions in large workspaces. Technologies and skills demonstrated: - VFS architecture, Project View customization, and dynamic UI refresh patterns. - External build system integration and project structure modeling (ProjectRootEntity). - Performance tuning, memory management, safe modification tracking, and indexing reliability improvements. - Code cleanliness, test stability, and logging practices (WorkspaceModel.eventLog).
