React in 2026: what "senior" actually means

A lot of "senior React" résumés stopped learning around 2021. When we say senior, we mean someone who kept going.

Start with Server Components and the App Router. A senior engineer knows what "use client" actually costs, knows where data fetching belongs, and can build a page that loads fast without shipping the whole app to the browser. They also know when you don't need Next.js at all — an internal tool behind a login is usually better off as a plain Vite SPA, and saying so is a sign of judgment, not laziness.

Then there's state. Less experienced engineers reach for Redux, or a tower of context providers, by reflex. The better instinct is restraint: server state handled by something like TanStack Query, a little local UI state, and very little that's truly global. Reaching for Zustand instead of a sprawling Redux setup usually means someone has had to maintain a large React codebase, not just start one.

Last, performance. memo, useMemo and useCallback aren't free, and scattering them everywhere is a tell. A senior developer profiles first, then fixes the thing that actually re-renders. That judgment is most of what we screen for, and it's the part a CV never shows.

How we vet React engineers

Hiring React talent is the most crowded corner of the developer market, which is exactly why a portfolio and a friendly call tell you almost nothing. Our screen is built to show judgment under realistic conditions.

It runs in four parts. First, a component-API design exercise: we hand over a real-ish feature and watch how the candidate designs the interface — props or context, controlled or uncontrolled, where state lives, how it gets reused and tested. Good engineers design the seams before they write any markup.

Second, performance reasoning. We give them a component that re-renders too often and ask them to diagnose it. We're listening for whether they profile and reason, or whether they wrap everything in memo and hope.

Third, accessibility. Keyboard navigation, focus management, semantic HTML, sensible ARIA — part of "done," not a later ticket. A custom dropdown that traps keyboard users fails the bar no matter how clean the code looks. Fourth, testing: unit tests in Jest or Vitest and integration tests in React Testing Library, written with the feature and aimed at behaviour rather than brittle internals.

If you want to run the same bar yourself, our guide to hiring React developers walks through the whole process.

Why we default to Next.js

When we start a new React build, the default is Next.js — and we'd rather explain why than treat it as fashion.

The honest reason is server rendering done well. For anything public — marketing sites, content, storefronts, signed-out product pages — SSR and static generation give you fast first paint and clean indexing without the hydration penalties older setups carried. The App Router keeps most of a page on the server and ships only the interactive parts to the browser. On a mid-range phone, that's the gap between snappy and sluggish.

The proof is the site you're reading. We rebuilt squashapps.com on React and Next.js in 2026, and it ships with all-green Core Web Vitals — the same bar we hold client work to. That's our own production site, not a number from a vendor's blog.

Next.js is a default, though, not a rule. SSR earns its keep when first load and SEO matter; it also brings a Node runtime, caching decisions and deployment nuance that a logged-in dashboard simply doesn't need. For those we'll recommend a lighter Vite SPA. Knowing when the heavier tool is the wrong call is part of what you're hiring.

React in production

Here's the same story told through real engagements instead of adjectives. Every figure below comes from a project in our case-study record.

HealthTech SaaS Australia — React inside a delivery turnaround

An Australian HealthTech company building clinic-management and patient-records software was stuck at two engineers and couldn't keep up with its own roadmap. We embedded a pod — .NET Core on the backend, React on the web, Flutter on mobile, all on Azure. The React work mattered: we moved the appointment-scheduling interface, the most-used screen in the product, off legacy jQuery and onto a modern React component architecture, which unlocked UX work the old code had blocked for over a year. We also built a component library on Radix UI primitives with a healthcare design system on top. Shipping went 4× faster, production bugs fell 50%, and the team grew from 2 to 12 without the usual communication tax. Their CTO put it simply: "They rebuilt our engineering foundation while simultaneously shipping product." Read the case study →

Hydesq — a full React product, end to end

Hydesq is an Australian desk-booking startup. The founder brought a concept and a design; we built the product. That meant a React admin dashboard — live floor-plan view, booking management, zone and resource config, and a reporting module for utilisation by zone, team and day — plus a React Native employee app and a Node.js/PostgreSQL backend serving both from one API. The work earned a 5.0 Clutch rating and rolled into ongoing maintenance. Read the case study →

Garuda — React in production since 2018

We don't only build React for clients; we run it ourselves. Garuda, our clinic-management platform, has had a React web frontend in continuous production since 2018, serving real clinics every day alongside a Flutter patient app on a shared Node.js API. Maintaining a React frontend across that many versions, for that long, is where a lot of our opinions about what ages well come from.

Design systems and accessibility

A growing product collects UI debt unless something holds the line. That something is a real design system plus an accessibility bar that's enforced rather than aspirational.

We build typed component libraries documented in Storybook, so a button, a form field or a data table is defined once and reused everywhere instead of being rebuilt slightly differently by each engineer. That's what kept the HealthTech platform visually consistent while its team quadrupled. It's also where accessibility scales: get focus, keyboard support and semantics right in the shared Select or Dialog, and every screen that uses them inherits it.

Our default is WCAG 2.1 AA — keyboard-operable, visible focus, enough contrast, correct semantics, and ARIA only where native elements can't do the job. When a build needs dedicated design depth next to the engineering, we pair React teams with our UX and design specialists.

How you engage us

You can hire one dedicated React engineer to extend your team, or a full pod — React plus backend, mobile, QA and a PM — to own a build end to end. Hydesq and the HealthTech engagement above were both pod-shaped. Either way, the engineers join your standups, your board and your code reviews. We run integrated, not as a separate offshore track.

Pricing follows our standard dedicated-engineer model, starting at $10k/month for a single senior engineer, with hourly and fixed-price options for shorter or scoped work. React rarely ships alone, so most builds pair it with a backend and often mobile — see Node.js, .NET, React Native and full-stack engineers, all part of our staff augmentation model.

Frequently asked questions

Can I interview developers before hiring?

Absolutely. You interview, optionally run a paid test sprint, and only commit when you're satisfied. No pressure.

What pricing models do you offer for React engineers?

Monthly retainer for ongoing work, starting at $10k/month for a single senior engineer. Hourly for short engagements. Fixed-price for project-scoped work.

What tools do your React developers use?

Jira, GitHub, GitLab, Linear, Slack, Notion — we adapt to your stack, not the other way around.

Are developers full-time on our project?

Yes — dedicated full-time, not shared across clients.

Can we scale up or down?

Scale up with new engineers onboarded in 48h. Scale down with two weeks notice. No contractual lock-in.

Do your React engineers know Next.js App Router?

Yes. All new builds use Next.js 14 App Router with TypeScript. We also maintain legacy Pages Router projects where needed.

Can they work with our existing design system?

Yes. We integrate with Figma, Storybook, or your in-house component library. We can also build a design system from scratch.

Do they write tests?

Unit tests (Jest, Vitest) and integration tests (React Testing Library) are part of our definition of done — not an afterthought.

App Router or Pages Router for an existing codebase?

It depends where you are. If you're on a healthy Pages Router app, we usually don't recommend a wholesale rewrite. We migrate route by route where there's a concrete win — a slow public page, or a section that needs server components — and leave the rest stable.

Do you do React performance audits as a standalone engagement?

Yes. If you don't need ongoing engineers but your React app feels slow, we'll profile it, find the real bottlenecks — unnecessary re-renders, oversized bundles, weak data-fetching, Core Web Vitals issues — and hand back a prioritised plan. We'll execute it too if you want.

React with which backend?

Whatever fits. We pair React most often with Node.js for JavaScript-everywhere teams and real-time features, and with .NET for enterprise or regulated work — the HealthTech platform in our case studies runs React on a .NET Core API.

Can you migrate our Create React App project to Vite or Next.js?

Yes, and it's common work — CRA is effectively end-of-life. We move SPAs to Vite for faster builds, and to Next.js when SSR and SEO are in scope. The migration is incremental and test-backed, not a big-bang rewrite.
