ReSharper - Code Styles and Cleanup (C#)- Introduced a clear separation between code style and code formatter subsystems.- Led the development of code style inspections, suggestions, and the code cleanup subsystem, encompassing new features, bug fixes, and customer communications.- Successfully ported the initial support for the code cleanup feature to Rider.ReSharper - Trigram Index / Text Search (C#)- Reimplemented the core Word Index (integral to ReSharper/Rider code intelligence) from scratch using a custom-developed indexing algorithm based on trigrams.- Developed an ultra-fast direct text search leveraging the new trigram index, which, thanks to a bespoke hashing algorithm, also supports searches for two-symbol and single-symbol sequences.Rider - WPF Preview (C#/Kotlin)- Engineered a fast and responsive out-of-process visual preview for WPF XAML files.Rider - WinForms Editor (C#/Kotlin)- Created an internal library for re-hosting Win32/GDI windows within Java AWT applications.- Managed a development team comprising two interns.- Architectured and developed the core functionality of the WinForms editor, integrating an external designer process (and window) into Rider’s Swing frontend.New Product R&D (Kotlin)- Spearheaded multiple projects including an IntelliJ-based plugin, a desktop app with a web UI, and plugins for Space and TeamCity.- Employed both Kotlin2JS and Kotlin2JVM for project implementations.Participation in Several Internal Hackathons- Conceptualized a diagnostic application to enhance the support experience for customers.- Enhanced a product to assist support engineers in maintaining real-time communication with customers through instant messaging.- Invented an image processing algorithm that enables users to identify desired image regions through simple inputs, such as a drawn line (image completion).

Was in charge of developing a UI framework for interactive TV-apps running in a cloud. Like a Google Stadia (which wasn’t introduced at that time) but for television, sports, and entertainment.Team and process:* Team of 9 developers built from the scratch* Introduced high coding standards and code review process* Stable Scrum process and application lifecycle management right from the beginning* QA engineers were “borrowed” from QA department to be a part of the team* Mandatory unit-testing and test automation.* Multi-step CI system - compilation pre-check, unit tests, visual UI tests (over video feed!)* Automated performance testing (on daily basis)* Supporting product teams developing apps based on our frameworkProduct:* WPF inspired XAML-based UI framework for interactive TV-apps - remote machine rendering, more advanced Dependency Property System* Full set of UI components and different layout panels* Deployment via NuGet (not mainstream at that time)* Visual Studio Extension with project templates, custom run options, integration with the debugger.* High-performance with less boxing and memory usage, a custom dispatcher with non-preemption dispatching of the “main” thread task * Remote rendering - apps running on one machine - rendering occurs on others* Stateful apps - automated state management (preserving and loading) as part of the frameworkParticipating in exhibitions and demonstrating products:* IBC 2013 (Amsterdam)* IBC 2014 (Amsterdam)* MIPCOM 2013 (Cannes, France)* NAB Show 2014, (Las Vegas)
