Olga Larina developed and maintained core features and testing infrastructure across the SurveyJS repositories, including survey-creator, survey-library, and survey-analytics. She delivered UI enhancements, dynamic data visualization such as radar charts with Plotly.js, and improved theming through CSS custom properties. Olga stabilized CI/CD pipelines, automated Playwright-based visual regression testing, and refactored frontend logic in TypeScript and JavaScript to reduce technical debt. Her work addressed cross-device UI consistency, streamlined developer workflows, and strengthened test reliability. By integrating localization, accessibility, and robust configuration management, Olga ensured the codebase remained maintainable and adaptable, supporting both end-user experience and ongoing engineering velocity.

October 2025 was focused on strengthening the reliability and observability of the Toolbox-related workflows in survey-creator, with a dual emphasis on added debugging instrumentation and stabilizing test automation for screenshot-based validation. The work improved visibility into toolbox state during RTL and compact mode, and reduced flaky test behavior by aligning load timing with DOM readiness.

July 2025 monthly summary for surveyjs/survey-analytics: Key feature delivered is the radar chart visualization for ranking question types in the analytics tool, implemented with Plotly. This includes Plotly setup adjustments, hover templates, color schemes, and localization support to ensure a consistent and localized analytics experience. Major bug fixed: unregisterVisualizer now correctly handles prototype inheritance during unregistration, with an added dedicated test to verify that visualizers are removed and re-added as expected. Overall impact includes improved analytics capabilities, reliability, and localization readiness, enabling clearer business insights and more robust visualization components. Technologies/skills demonstrated include Plotly integration, frontend visualization patterns, test coverage, localization, and understanding of prototype inheritance semantics.

April 2025 monthly summary for survey-js repositories. Key features delivered include Dropdown/TagBox dynamic option creation from user input in survey-library and a refactor of QuestionSelectBase.calcVisibleChoices for clarity. Major UI fixes addressed mobile font-size resets, stabilizing cross-device behavior, and a read-only text localization fix in logic operators for survey-creator. QA and testing gains were accelerated with Playwright-based automated screenshots for survey flows. Code quality and tooling were strengthened with lint-staged setup and broad lint improvements across Vue 3 and React. In survey-creator, modal behavior improvements for the Property Grid Editor were implemented. Overall impact: reduced friction for end users, improved cross-platform UX consistency, and higher release confidence through automated validation. Technologies/skills demonstrated: TypeScript/JavaScript, Vue 3, React, ESLint, lint-staged, Playwright, and cross-repo QA practices.
