Over a two-month period, contributed to JetBrains/ij-perf-report-aggregator and Kotlin/kotlin-lsp by engineering performance dashboards and enhancing metric observability. Focused on backend and frontend development using TypeScript, Vue.js, and Kotlin, the work included refactoring GoLand dashboards to a data-driven architecture, standardizing chart units, and improving metric descriptions for clarity. Implemented features such as interactive popovers for metric information, UI lag monitoring, and comprehensive engine comparison views with heatmaps. Addressed reliability through bug fixes and test improvements, while also refactoring tracing context propagation in Kotlin/kotlin-lsp to streamline context management using coroutines and OpenTelemetry instrumentation.
