What Does a Frontend Developer Actually Do?

Frontend Developers craft the visual and interactive layer of web applications, translating design mockups and user stories into performant React or Vue code. They typically work within product teams at tech companies like Stripe, Revolut, and Spotify, reporting to Engineering Managers or Tech Leads. Daily responsibilities include writing component-based UI code, optimizing bundle sizes, ensuring WCAG accessibility compliance, writing unit and integration tests, and collaborating with designers and backend engineers via Figma and pull request reviews.

What Recruiters Look For

Recruiters want to see 3+ years of production React or Vue experience, demonstrable performance optimization skills (with numbers), and WCAG accessibility knowledge. They value candidates who've shipped features to millions of users, not just hobby projects. Strong problem-solving ability is proven through bug fixes and refactoring stories. Portfolio matters—a GitHub repo showing clean code, tests, and documentation outweighs a list of frameworks. Bonus points: TypeScript expertise, familiarity with CI/CD, mentoring junior engineers, and contributions to open-source.

Key Skills to Include

Core technical skills: React 18+, Vue 3, TypeScript, CSS3/Tailwind, responsive design, and web performance (Core Web Vitals, bundle analysis). Testing frameworks: Jest, React Testing Library, Cypress. Build tools: Webpack, Vite. API integration: REST, GraphQL. Accessibility: WCAG 2.1, semantic HTML, ARIA. Version control and CI/CD. Soft skills matter equally: communication with designers, collaboration with backend teams, and mentoring. If you have experience with Storybook, design systems, or A/B testing, add those. Avoid listing every framework you've touched—be selective and deep.

Common Mistakes

Don't claim expertise in 10 frameworks—specialize in 2–3. Avoid vague bullet points like 'improved UI' or 'worked with React'; instead quantify: 'reduced FCP by 28% through code-splitting.' Never skip testing—omitting Jest or Testing Library from your CV suggests you don't write production-quality code. Don't oversell junior projects. Don't ignore accessibility—it's no longer optional. Don't list skills without recent usage. Don't say 'full-stack' unless you genuinely own backend APIs. Finally, avoid design jargon without substance; focus on engineering impact.

Formatting Tips

Use a clean, single-column CV template with ample whitespace. Highlight metrics in bold: '40% faster,' '$2.5M ARR.' Group skills by category: Languages, Testing, Build Tools, Design. Keep bullets to 12–20 words; recruiters scan in 6 seconds. Use action verbs: Built, Optimized, Refactored, Mentored. Include a GitHub link (ensure it's current and shows 3+ well-documented repos). Link to a live portfolio or Storybook instance if possible. Use consistent date formatting (e.g., 'Jan 2023'). Avoid graphics that don't render in ATS systems. PDF export should be sharp and ATS-friendly.

Top 5 Interview Questions — Frontend Developer

1Walk us through how you'd optimize a React app with a 5MB bundle size and 4.2s LCP. What tools would you use?
I'd start by profiling with Webpack Bundle Analyzer to identify large dependencies. Then I'd implement code-splitting at route level using React.lazy, remove unused libraries, and lazy-load images with Intersection Observer. I'd switch from moment.js to date-fns, minify CSS, and enable gzip compression. Finally, I'd measure Core Web Vitals using Lighthouse and set up continuous performance monitoring in CI/CD to catch regressions early.
2How do you ensure your components are accessible to screen reader users?
I follow WCAG 2.1 AA standards: using semantic HTML (button, nav, main), adding proper ARIA labels and roles where needed, ensuring color contrast of 4.5:1, managing focus with tabindex, and providing keyboard navigation. I test with axe DevTools and NVDA screen reader, write tests with Testing Library (which encourages accessible queries like getByRole), and audit with Lighthouse. Accessibility is part of my definition of 'done'.
3Describe a time you debugged a complex performance issue. What was the problem and how did you solve it?
At Stripe, users reported cart slowness on mobile. Chrome DevTools showed rendering was taking 200ms per keystroke in the quantity input. I found an unoptimized re-render loop—the parent was re-rendering the entire form on every input change. I refactored using useCallback to memoize handlers and split state into smaller contexts. This cut re-render time to 20ms. I then added React.memo to child components and implemented virtual scrolling for large cart tables, improving perceived performance by 60%.
4What's your approach to testing React components? What tools do you prefer and why?
I use Jest for unit tests and React Testing Library for integration tests. I avoid testing implementation details (like state updates); instead, I test behavior from the user's perspective. For example, I query by role and label, not by className. I aim for 80%+ coverage, prioritizing critical user flows. For async operations, I use waitFor. I also write snapshot tests sparingly—only for visual components unlikely to change. E2E tests with Cypress cover full user journeys.
5How do you stay current with frontend trends like new React patterns or CSS features?
I follow newsletters like Frontend Weekly and Pony Foo, attend monthly London JavaScript meetups, and read RFC discussions in React GitHub. I experiment with new patterns in side projects—I recently built a small app with Server Components to understand the shift from client-side rendering. I also code review aggressively to learn from teammates. Staying current isn't about chasing hype; it's about understanding why a tool solves real problems.

How to Tailor Your CV

Top tech companies hiring Frontend Developers include Stripe (emphasis on performance and component architecture), Revolut (high-scale payment systems with Vue/React), Deliveroo (mobile-first UX and real-time updates), Booking.com (accessibility and internationalization), and Cloudflare (modern tooling and DevEx). For Stripe, highlight your obsession with performance metrics and system design. For Revolut, showcase payment or fintech experience and Vue expertise. For Deliveroo, emphasize responsive design and real-time features. Always quantify improvements—'improved LCP by 35%' beats 'optimized performance'. Tailor your GitHub projects to show the company's tech stack.
