• —CRM for operators on Nuxt 3 (SSR), TypeScript, TanStack Query, WebSocket: templated ticket processing scenarios. Based on CRM logs before/after - ticket processing time -50%, operator errors -30%. Personal contribution: scenarios, WebSocket integration, query optimization.
• —Dynamic forms system on Nuxt 3 (Composition API, Pinia): advanced validation and state management. Based on form events and logs - form completion time -35%, validation errors -40%.
• —Analytics dashboard on Vue 3: large data visualization, list virtualization, render optimization. Report generation became 3x faster (measured report preparation time before/after).
• —Personalized missions module with a progress tracker: repeat visits +28%, conversion to completed tasks +45% (based on product analytics before/after).
• —Developed the design system and shared component library; optimized Core Web Vitals (LCP, INP, CLS); set up Sentry monitoring (releases, source maps, error triage); established the testing process: Vitest (unit), Playwright (e2e); conducted code reviews and mentored juniors.

• —Performance optimization: implemented lazy-loading, code splitting, and CDN for key pages (5), which qualitatively improved LCP (based on RUM measurements before/after). Reduced bundle size and origin load (confirmed by infrastructure team data).
• —Cross-browser forms: developed adaptive forms with validation on Nuxt 2 + Vuex, including IE11 support. Reduced the share of errors on submission (based on form_field_error events and logs).
• —Real-time interfaces: implemented WebSocket interaction with reconnect, authorization, and fallback to long polling. Set up monitoring via Sentry (source maps, releases).
• —Legacy migration: gradually migrated ~20 components from Options API to Composition API (Vue 2.7), covering them with Jest tests before refactoring. Ensured transition without regressions.
