React & frontend engineering
Ship UI without the rewrite cycle. React engineers who ship production UI.
Slow bundles, hydration mismatches, and untested components quietly consume sprint capacity. We staff React engineers who ship Next.js apps with measured LCP gains, wire typed clients to your OpenAPI specs, and extend design systems without one-off CSS in feature branches. Releases stay predictable because performance and contract breaks surface in CI, not in prod.

Deep-Dive Tech Stack
Frontend quality is a stack problem: components, routing, types, styling, state, and tests either reinforce the same contracts or fight each other. We match engineers who understand server and client boundaries, not only hook syntax.
-
React
Component architecture with clear server and client boundaries and hooks used without stale closure bugs. Re-render storms from context misuse get fixed with composition; memoization lands only where profiling proves it matters.
-
Next.js
App Router patterns, SSR versus ISR for SEO and freshness, streaming, and API routes that do not become accidental backends. They avoid waterfall fetching that kills TTFB and choose static export versus server render with explicit tradeoffs.
-
TypeScript
Strict mode and types generated from OpenAPI or GraphQL schemas. Breaking API changes fail CI before merge when shared types document the contract with backend teams.
-
Tailwind CSS
Design token integration and component variants without unmaintainable class strings. Patterns extend your system with documentation instead of arbitrary values that break consistency as the product grows.
-
Redux / Zustand
Predictable state for checkout, wizards, and real-time dashboards without global stores that re-render the tree on every keystroke. URL state and React Query cache win when another reducer would add noise.
-
Testing Library & MSW
User-centric tests with MSW handlers mirroring real API shapes. Flaky tests get quarantined with owners; timing and data setup are fixed instead of retry-until-green in CI.
-
Storybook & performance
Component documentation, visual regression hooks, and bundle analysis before merge. Code-splitting and image optimization often cut bundle size 30%+ when LCP and CLS are measured, not assumed.
-
TanStack Query
Server-state caching, stale-while-revalidate, and optimistic updates with rollback on failure. Duplicate fetches and waterfall requests on dashboard pages drop when query keys and prefetching are aligned to user navigation patterns.
-
Vite & bundling
Fast dev server with HMR, production builds with code splitting and tree shaking, and bundle analysis in CI on critical routes. Slow builds that discourage small PRs get fixed with dependency audit and lazy route loading, not by skipping checks.

Frontend staffing, answered plainly
How do you handle time-zone crossovers?
We book 3–4 hours of overlap for standups, design reviews, and pairing sessions. Async Figma comments and Loom walkthroughs cover the rest so your US or EU leads aren't stuck in midnight calls.
Do your engineers follow our design system?
Yes. We work inside your tokens, components, and Figma specs. If the system has gaps, we extend it with documented patterns instead of one-off CSS in feature branches.
What is your code review process for UI code?
Reviews cover accessibility, test coverage, bundle impact, and API contract alignment. Visual changes include before/after notes or Storybook links so reviewers aren't guessing from a diff alone.
Can you work with our existing backend APIs?
We integrate with your REST or GraphQL contracts, generate or maintain typed clients, and flag breaking changes early. We don't mock forever and defer integration to "phase two."
Who owns the IP and commits?
You do. All UI code lives in your repositories under your terms. We don't retain components or reuse your product logic across clients.
