TL;DR
React + TypeScript is the baseline for most frontend roles in 2026. Show performance metrics (Core Web Vitals, Lighthouse, bundle size). Include GitHub and live project links. Quantify impact: load time improvements, conversion lifts, accessibility compliance.
Tech Stack Presentation
Frontend development has a large and evolving ecosystem. Organize your skills clearly so hiring managers can quickly see what you bring to the table.
Example Technical Skills Section:
Languages: TypeScript, JavaScript (ES2024+), HTML5, CSS3
Frameworks: React, Next.js, Vue 3 (familiar)
Styling: Tailwind CSS, CSS Modules, Styled Components, Sass
State Management: Zustand, React Query (TanStack Query), Redux Toolkit, Context API
Testing: Vitest, React Testing Library, Playwright, Cypress
Build Tools: Vite, Webpack, Turbopack, ESLint, Prettier
Other: GraphQL, REST APIs, WebSockets, Git, CI/CD, Storybook, Figma
TypeScript Is No Longer Optional
- TypeScript is expected. Most frontend job postings in 2026 list TypeScript as required, not preferred.
- Show depth, not just familiarity. Mention generics, utility types, strict mode, type guards if applicable.
- Framework versions matter. "React" is fine, but "React 18+ (Server Components, Suspense)" shows you stay current.
- List what the job asks for first. Mirror the order of technologies in the job description.
Performance Metrics That Impress
Performance optimization is one of the highest-value skills a frontend developer can demonstrate. Hiring managers love concrete before-and-after metrics.
Weak:
Improved website performance and load times
Strong:
Reduced Largest Contentful Paint from 4.2s to 1.1s through code splitting, image optimization (WebP/AVIF), and edge caching-improving Lighthouse performance score from 45 to 96
Weak:
Optimized React application
Strong:
Cut initial bundle size by 60% (1.2MB to 480KB) using dynamic imports, tree shaking, and migrating from Moment.js to date-fns, reducing time-to-interactive by 2.3 seconds on mobile
Weak:
Fixed rendering issues
Strong:
Eliminated unnecessary re-renders across 15 components using React.memo, useMemo, and virtualized lists (react-window), improving scroll performance from 12fps to 60fps on product listing pages
Performance Metrics to Track and Include
- Core Web Vitals: LCP, FID/INP, CLS improvements
- Lighthouse scores: Performance, accessibility, SEO, best practices
- Bundle size: Total JS delivered, code splitting impact
- Load times: Time-to-interactive, first meaningful paint
- Runtime performance: Frame rates, memory usage, rendering efficiency
- Business impact: Conversion rate changes tied to performance improvements
Side Projects and Open Source
Frontend development is one of the best fields for demonstrating skills through side projects. Live, deployed projects are worth more than any certification.
Projects Section Example:
Projects
TaskFlow | taskflow.dev | github.com/jchen/taskflow
- Built full-stack task management app with Next.js 14 (App Router), TypeScript, and Tailwind CSS
- Implemented real-time collaboration using WebSockets and optimistic UI updates
- 1.2K GitHub stars, 200+ monthly active users
Open Source: react-virtual-table | github.com/jchen/react-virtual-table
- Created virtualized table component handling 100K+ rows with sorting, filtering, and column resizing
- 800+ weekly npm downloads, used by 3 production applications
Making Projects Count
- Deploy your projects. A live URL is 10x more impactful than a GitHub repo alone.
- Include metrics: GitHub stars, npm downloads, users, or any adoption numbers.
- Quality over quantity. 2 polished projects beat 10 half-finished ones.
- Show modern patterns. Use current best practices-TypeScript, server components, proper testing.
- Write good READMEs. Hiring managers will judge your documentation as much as your code.
Responsive Design and Accessibility
Responsive design is expected by default, but accessibility expertise is a genuine differentiator. Companies are increasingly prioritizing a11y compliance, and developers who understand it are in high demand.
Weak:
Ensured website was responsive on different devices
Strong:
Implemented responsive design system supporting 5 breakpoints (mobile through ultrawide), achieving consistent experience across 15 device types and reducing mobile bounce rate by 22%
Weak:
Improved accessibility
Strong:
Led WCAG 2.1 AA compliance initiative: audited 40+ pages, fixed 200+ issues (semantic HTML, ARIA labels, keyboard navigation, focus management), passing third-party accessibility audit with zero critical findings
This kind of work sits right next to design - if you spend more time in design systems, user research, and interaction design than in implementation, our UX designer resume example is the better fit for how to frame it.

Portfolio Links and How to Present Them
Your portfolio is proof of what you can build. Here is how to present it effectively:
- Personal site: Build it with modern tools (Next.js, Astro). It is itself a portfolio piece.
- GitHub profile: Pin your best repositories. Write clear READMEs. Clean up commit history.
- Live deployments: Host projects on Vercel or Netlify with custom domains when possible.
- Code quality: Ensure pinned repos demonstrate clean code, proper TypeScript, testing, and documentation.
Portfolio Red Flags to Avoid
- Broken links. Test every URL on your resume before submitting.
- Tutorial clones. "Netflix clone" or "Todo app" without significant original additions signals beginner level.
- Empty GitHub. An inactive profile with no recent commits can hurt more than help.
- Unfinished projects. Only link to polished, completed work.
Common Frontend Resume Mistakes
Mistakes That Get Frontend Resumes Rejected
- Listing every technology ever used. Focus on what you can discuss confidently in an interview.
- No TypeScript in 2026. If you only list JavaScript, hiring managers will wonder why.
- Missing performance metrics. Frontend is about user experience-show you measure it.
- No live projects or GitHub. Frontend work is visual and demonstrable. Show it.
- Ignoring accessibility. a11y expertise is increasingly required, not nice-to-have.
- Feature descriptions without impact. "Built dashboard" vs "Built dashboard reducing reporting time by 4 hours/week."
