FRONTEND FAQ
What tech leaders ask about our Frontend development services:
Our core expertise lies in the React and Vue.js ecosystems. We extensively use Next.js and Nuxt for enterprise-grade applications requiring Server-Side Rendering (SSR), and we also maintain deep expertise in Angular for legacy enterprise modernizations.
We strictly adhere to Google's Core Web Vitals. We optimize load times by implementing advanced techniques like route-level code splitting, lazy loading of heavy components, aggressive image optimization, and Edge caching strategies.
Yes, we specialize in Progressive Web Apps (PWAs). By leveraging Service Workers and IndexedDB, we build resilient web applications that can function offline, sync data when reconnected, and deliver a native-app-like experience in the browser.
State management can make or break a large app. Depending on the architecture, we utilize Redux Toolkit for complex global state, Zustand for lightweight reactivity, and React Query/SWR for robust server-state synchronization and caching.
Absolutely. We often work alongside design teams to translate Figma files into strictly typed, reusable React component libraries. We use Storybook to document the components and Tailwind CSS or CSS-in-JS for scalable styling.
Accessibility is built-in, not bolted on. We engineer our components to be WCAG 2.1 AA compliant by default, utilizing proper semantic HTML, WAI-ARIA attributes, focus management, and keyboard navigation testing.
We implement a rigorous testing pyramid. This includes unit testing business logic with Jest or Vitest, testing component behavior with React Testing Library, and validating critical user flows via end-to-end (E2E) testing with Cypress or Playwright.
Yes, we excel at incremental modernization. We often employ the strangler fig pattern or Micro-Frontend architectures (using Webpack Module Federation) to slowly carve out and replace legacy UI code without disrupting your active users.
