Remember the 2nd review I mentioned above? Now we're optimizing for that. This is the
last thing that stands between you and an interview. Recruiters will review your resume in
more detail at this stage, but 95% of the screening decision is made on the most
recent role.
That's logical: your most recent role should be the most representative of your current
seniority, abilities, and responsibilities. To get recruiters to say "yes", you need
to cover the entire role profile for a Front-End Developer, with one
dedicated bullet point for each of the areas we listed in the Profile Summary's Domain
Expertise bullet.
1
Modular UI Development
You build the UI from reusable, composable components. Hiring managers look here to see whether the rest
of the team can build on your code, or whether they'll be stuck untangling it later. Talk about how
you used patterns like prop contracts and slots (React, Vue, or Storybook) to get your components reused
across teams instead of rebuilt from scratch.
Techniques
Composable APIs
Prop contracts
Slot patterns
Container/presentational
Headless components
Tools
React, Vue, Svelte
Tailwind CSS, CSS Modules
Storybook, Bit
Metrics
Component reuse rate
Design-system adoption %
Story coverage %
2
State, Data Flow & Client Architecture
You architect client state and data flow that stays predictable as the app scales. It matters because
sloppy state handling is where most front-end bugs come from, so hiring managers want to see you keep it
under control as the app grows. Show them how you used a state store and a data-fetching library like
Zustand and TanStack Query to split client and server data cleanly and bring the re-render count down.
Techniques
Client/server split
Cache invalidation
Suspense boundaries
Optimistic updates
Tools
Redux Toolkit, Zustand, Jotai
TanStack Query, SWR, RTK Query
Metrics
Cache hit rate
Form completion %
Re-render count
3
Performance & Optimization
You make the app fast under real load, on first paint and every interaction. Slow pages lose users and
revenue, and it's one of the few things a hiring manager can measure directly, so it carries
weight. Write about how you used code splitting and lazy loading, tracked in Lighthouse or RUM, to bring
down your Core Web Vitals like LCP, INP, and CLS.
Techniques
Code splitting
Lazy loading
Server components
Hydration discipline
Tools
Lighthouse, WebPageTest, RUM
Webpack, Vite, Turbopack
Next.js Image, Cloudinary
Metrics
LCP, INP, CLS
JS bundle size, hydration time
4
Accessibility, Usability & UX Quality
You design for every user, keyboard and screen reader included. It matters to hiring managers on two
fronts: it's a legal requirement in many markets, and accessible sites tend to convert better.
Mention how you used semantic HTML and screen-reader testing, with tools like Axe and VoiceOver, to hit
WCAG 2.2 AA and bring the open issue count down.
Techniques
Semantic HTML
ARIA patterns
Focus management
Screen-reader testing
Tools
Axe, WAVE, Lighthouse a11y
NVDA, VoiceOver, JAWS
Metrics
WCAG 2.2 AA pass
Axe issue count
A11y closure rate
5
Integration with APIs & Back-End Systems
You wire the front end to back-end services and handle failures gracefully. Most of the hard front-end
bugs live at this boundary, so hiring managers want proof the UI still works when a request breaks. Let
them know how you used auth flows, retries, and schema validation, with tools like Axios, Apollo, or
Zod, to keep the UI working when requests failed and cut the API error rate.
Techniques
REST integration
GraphQL queries
Auth flows
Schema validation
Error boundaries
Tools
Fetch, Axios, ky
Apollo, urql, Relay
Zod, Yup, Valibot
MSW, OpenAPI codegen
Metrics
API error rate
P95 latency
Retry success rate
6
Testing, Reliability & Observability
You catch regressions before users do, with layered tests and real monitoring. Hiring managers read it
as the clearest sign you can be trusted with code that stays stable, not just code that works on your
machine. Point out how you used layered tests and production monitoring, with tools like Playwright and
Sentry, to cut production errors and bring your fix time down.
Techniques
Unit tests
Component tests
E2E tests
Visual regression
Tools
Vitest, Jest, Testing Library
Playwright, Cypress
Sentry, Datadog RUM, LogRocket
Metrics
Coverage %
MTTR
Production error rate
Flaky test rate
7
Build Systems, Tooling & CI/CD
You own the tooling that moves code from commit to production. Good tooling makes the whole team faster,
so owning it tells a hiring manager you think past your own code. Spell out how you used CI pipelines
and preview deploys, set up in GitHub Actions or Vercel, to cut build time and let the team ship more
often.
Techniques
Monorepo setup
CI pipelines
Preview deploys
Bundle budgets
Tools
Vite, Turbopack, esbuild
Turborepo, Nx, pnpm
GitHub Actions, Vercel, Netlify
Metrics
Build time
CI duration
Deploy frequency
8
Collaboration & Delivery Processes
You work with a team to merge and release code safely. Companies promote the people who make releases
smoother, not just the ones who write features, so hiring managers look for it. Tell them how you used
PR reviews and feature-flag rollouts, with tools like GitHub and LaunchDarkly, to ship changes without
breaking things for users.
Techniques
PR reviews
RFC writing
Design-system contributions
Feature flag rollouts
Tools
GitHub PRs, GitLab MRs
Figma, Zeplin
LaunchDarkly, Statsig
Linear, Jira
Metrics
PR review SLA
