Ilia Zakoulov developed and integrated a non-modal Welcome Screen and onboarding experience for JetBrains/intellij-community, focusing on PyCharm and GoLand. He refactored legacy components, modularized the welcome screen architecture, and introduced dynamic content providers using Kotlin and Java. By ensuring UI updates ran on the Event Dispatch Thread, he improved startup stability and responsiveness. Ilia automated Python project source root detection and enhanced telemetry for user interactions, supporting data-driven UX improvements. His work addressed JVM 21 compatibility, streamlined onboarding, and reduced maintenance overhead, demonstrating depth in IDE development, UI/UX design, and backend integration while delivering reliable, maintainable platform features.

October 2025: Delivered integrated Welcome Screen into the Misc Project Framework, stabilized the welcome/misc UX, and introduced a non-modal onboarding welcome screen. These changes streamline user access to PyCharm Welcome, improve new-user onboarding, and reduce unnecessary reloads, delivering measurable business value and reliability in the JetBrains/intellij-community repository.

Month: 2025-09 Concise monthly summary: In September 2025, contributed to onboarding and welcome-screen improvements in JetBrains/intellij-community, delivering user-facing features for PyCharm and stabilizing the Welcome Screen UX across JVM 21 while laying groundwork for future onboarding experiments. Key outcomes include: Key features delivered: - PY-82074: Non-modal Welcome Screen for PyCharm with PyMiscService, Learn IDE displayed in the editor tab, automatic left-pane enablement when the welcome screen file is selected, new actions under New..., custom icon, and plugin icon tint for non-modal Welcome Screen; added non-modal welcome screen entry to plugin-content.yaml. - IJPL-202286: Welcome Screen Core Improvements – Introduced WelcomeRightTabContentProvider, internalized classes, simplified non-modal welcome screen EP names, bundle pointer usage, OpenWelcomeScreenAction, improved focusing behavior, and API dump; removal of non-modal welcome screen from community modules. - IJPL-202286: Welcome Screen overhaul/refactor – Bundle regeneration, removal of obsolete providers/icons, JVM 21 compatibility, UI/behavior enhancements, experimental flag, and related cleanup (tips, API, dependencies, wording). Major bugs fixed: - PY-82074: Fix focusing of Learn IDE tab. - Fix miscellaneous button on the old welcome screen. - JVM 21 compile-related fixes and theme/background image handling improvements for Welcome Screen. - Do not launch WelcomeScreenProjectActivity in headless/CLI test environments. Overall impact and accomplishments: - Improved onboarding experience for PyCharm users with a non-modal, more discoverable Welcome Screen and related New... actions. - Increased stability and performance through UI/UX refinements, JVM 21 compatibility, and API bundle improvements. - Reduced maintenance burden via consolidation, internalization, and cleaner dependencies. Technologies/skills demonstrated: - IntelliJ Platform SDK (Kotlin/Java), JVM 21 compatibility, UI/UX design, internationalization/internalization, bundle management, API cleanup, and testability in headless/CLI contexts.

August 2025 performance summary: Delivered a platform-integrated overhaul of the non-modal Welcome Screen with dynamic content providers and XML-defined actions, enabling smoother GoLand integration and removing legacy components. Implemented automatic Python 'src' root detection at project root to simplify project setup. Strengthened startup UI stability by ensuring all UI updates run on the Event Dispatch Thread. Introduced usage telemetry for welcome screen interactions to inform product decisions and improve usability. These changes reduce configuration overhead, improve UX, and establish a scalable platform/module architecture for future work.
