React Development That Ships
React powers the most ambitious web applications on the planet. We've been building with it since 2018 - from simple dashboards to complex multi-tenant platforms.
React development services build the production frontend of web applications using React, TypeScript, and the surrounding ecosystem (React Query, Zustand or Redux Toolkit, React Hook Form, Tailwind CSS, Storybook, Vitest, Playwright, Vite). Borah Labs has been shipping React in production since 2018, across dashboards, multi-tenant SaaS platforms, real-time interfaces, data-heavy admin panels, and customer-facing product UIs. A typical React engagement runs 4-12 weeks, starts at $8,500, and includes the engineering disciplines that separate a React app you can maintain from one you fear: a clean component architecture, properly factored state, deliberate performance budgets, accessibility passes, a real test suite, and a design system you can build on for years. We work with React 19, React Server Components where they earn their keep, and the modern data-fetching primitives — and we'll tell you honestly when a project should be a Next.js app instead, when it should be a Remix app, or when a thinner Vite SPA is the right call.

Who this is for
Built for teams with one of these problems.
If your situation looks like one of these three, you'll feel at home with us.
B2B SaaS, vertical SaaS, internal tooling, fintech dashboards
Engineering manager at a B2B SaaS with a maturing frontend
Inherited a React codebase that's grown organically for 2-4 years. Wants a senior partner to land the design system, factor the state management, set the performance budget, and bring the test suite up to a level the team can rely on. Often a 6-12 week engagement that hands off to a strengthened in-house team.
Productivity tools, data analytics, collaborative software, dev tools
Product team building a complex interactive feature
Has a feature on the roadmap — real-time collaboration, drag-and-drop builder, 10K-row data grid, charting suite — that the existing team can't ship in the time available. Wants a senior React team to own that feature end-to-end: spec, build, ship, document, hand off.
Early-stage startups in any vertical with a serious frontend
Founder of a Series-A startup hiring before a hire
Knows the next senior React hire is 3-6 months away but the product can't wait. Wants a team that builds in the codebase, leaves it cleaner than they found it, and acts as a senior frontend voice in architecture decisions until the in-house hire is ready to take over.
Sound familiar?
- Your frontend codebase is a mess of prop drilling, global state, and components nobody on the team wants to touch — which means feature velocity has dropped from "weekly releases" to "please don't break anything."
- Your team can write React but the app is slow on real devices, hard to test, hard to onboard new engineers into, and the testing strategy is "we hope." The backlog of perf and refactor work keeps growing.
- You need a complex interactive UI — collaborative editor, scheduling tool, data dashboard with 10K rows, real-time chart — and your backend-led team doesn't have the frontend depth to land it without a senior partner.
How we solve it
- Clean component architecture with proper state separation (server state via React Query, UI state via Zustand or Context where appropriate), TypeScript end to end, and testing built in from the first week — not bolted on at the end.
- We ship reusable, documented component libraries (Storybook + design tokens + a Tailwind config your designers can read) that your team continues to extend after handoff. The system outlives the project.
- Performance-first development with explicit budgets: bundle size limits, lighthouse targets in CI, route-level code splitting, intentional memoization, virtualized lists, and image strategy. Real metrics on real devices, not localhost.
What you get
Deliverables, with sample artifacts.
Concrete outputs you can expect from this engagement — and a sample of what each one looks like.
Interactive Web Applications
Customer-facing or internal React applications with the level of interactivity that separates products from websites — real-time updates over WebSockets, drag-and-drop builders, data visualization with D3 or Recharts, optimistic UI, undo/redo, complex forms, file uploads, infinite scroll, virtualized lists. Built mobile-first, tested across browsers, accessible from day one.
Sample artifact
A deployed React application with a Storybook of every component, a Playwright test suite running in CI, and Lighthouse-budget enforcement on every PR.
Component Libraries
Reusable, documented design systems built on Tailwind CSS, Radix primitives, and headless UI patterns. Every component has variants, prop-driven sizing, dark-mode support, accessibility baked in, and a Storybook entry with usage examples. Designers consume the same tokens, engineers consume the same components, and your visual consistency stops drifting between teams.
Sample artifact
A versioned npm package (or workspace package), Storybook deployed at a subdomain you own, design tokens shared with your Figma library, and onboarding documentation for new engineers.
Dashboards & Admin Panels
Data-rich internal tools — admin panels, analytics dashboards, support consoles, ops dashboards — with charts, sortable filterable tables (10K+ rows handled smoothly), role-based access control wired into your auth, audit logs, and a UI that's actually pleasant to use eight hours a day.
Sample artifact
A deployed dashboard, RBAC matrix documentation, performance benchmarks against your real data volume, and a one-page launch readiness checklist signed off by stakeholders.
Frontend Architecture
When the React app is the bottleneck, we audit and rewrite the foundations — state management strategy, routing, data layer, error handling, suspense and streaming, testing approach, build pipeline, deployment. We document the resulting architecture so future engineers can reason about it without time travel.
Sample artifact
An architecture decision record (ADR) document, refactored core scaffolding shipped behind feature flags, a CI pipeline with build / test / lint / size budgets, and a 30-minute architecture walkthrough recorded for future hires.

Process
Week by week — what shipping looks like.
A typical engagement, end to end. Concrete deliverables every milestone.
Week 1
Audit & architecture
- Walk the codebase, the design system (or lack of one), the state management, and the testing posture.
- Identify the three highest-leverage architectural changes — usually state management, data fetching, or routing — and write the ADRs.
- Set explicit performance budgets (bundle size, LCP, INP) and accessibility targets that will gate every PR.
- Build a plan with concrete weekly deliverables, demo-able from week two.
Weeks 2-4
Build core scaffolding
- Land the foundational architecture — design system, state layer, data layer, routing, error boundaries, suspense.
- Set up Storybook with the first 10-15 components, theming, and a dark-mode toggle if relevant.
- Wire up CI: build, type-check, lint, unit tests, component tests, bundle-size guard, accessibility lint.
- Weekly working demos; each demo ships behind a feature flag to staging.
Weeks 5-8
Ship features
- Build the actual feature surface — interactive screens, dashboards, real-time updates, complex forms — on the foundation we shipped in weeks 2-4.
- Performance work as we go: virtualized lists, route-level code splitting, image strategy, memoization where the profiler says it matters (not before).
- E2E coverage with Playwright on the critical user paths; coverage targets locked at the architecture step.
- Continuous PR review with the in-house team so knowledge transfer happens during the build, not after.
Weeks 9-12
Polish, hand off, retainer option
- Accessibility pass with axe + manual screen-reader testing on the critical flows.
- Final performance pass against real-device data; budget enforcement on the production bundle.
- Documentation handoff: ADRs, component library docs, runbook, recorded architecture walkthrough.
- 30-day post-launch warranty; optional retainer for ongoing component-library and feature work.

Choosing a stack
When to pick what — and when to skip it.
The honest version. Real trade-offs, not marketing slideware.
React vs Next.js
See Workwize →When to use
Pure React (with Vite) for SPAs that are clearly internal tools — admin dashboards, embedded apps, kiosks — where SEO is irrelevant, where every user is authenticated, and where the simpler mental model and faster local dev are worth the trade.
When to avoid
Anything that needs SEO, anything that benefits from server rendering, anything with a marketing surface, or anything you might want to grow into a full product. Next.js is the safer default — see our Next.js development service for that workload.
Zustand vs Redux Toolkit
When to use
Zustand for most React apps in 2026. Tiny API, no providers, easy to test, easy to onboard new engineers into, and the patterns scale to large apps without ceremony. Pair with React Query for server state and you almost never need anything more.
When to avoid
Redux Toolkit only when you genuinely need its DevTools time-travel debugging, deeply normalized client state, or when the team is already deep into Redux patterns and the cost of switching outweighs the benefit. Don't pick Redux out of habit on a new project.
React Query vs SWR vs RTK Query
When to use
React Query (TanStack Query) is our default — best ergonomics, broadest community, deep mutation/optimistic UI support, and excellent TypeScript story. SWR is fine for simpler apps but has fewer escape hatches.
When to avoid
RTK Query only makes sense when you're already on Redux Toolkit and the integration is the tiebreaker. As a standalone choice for a new project, React Query wins on developer experience.
CSS-in-JS vs Tailwind vs CSS Modules
When to use
Tailwind CSS is our default in 2026. Zero runtime cost, design-token-friendly, fast iteration, and the file you read tells you exactly how the component looks. Pair with a tokens-driven Tailwind config and the @apply escape hatch where complex patterns repeat.
When to avoid
CSS-in-JS (Emotion, styled-components) carries real bundle and runtime cost in modern React, and the team usually ends up reinventing what Tailwind does. CSS Modules are fine for legacy migrations but rarely the right fresh choice.

Common questions
Everything you need to know about our react development that ships services.
Use Next.js when you need SEO, server rendering, edge or API routes, image optimization, or anything that touches a marketing surface — basically the safer default for any product that lives on the public internet. Use plain React (with Vite) when the app is purely authenticated, internal, or embedded — no SEO concern, no server rendering needed, and the simpler dev story is worth it. We help teams choose during scoping based on the actual constraints, not the hype cycle.
Yes — refactor and modernization engagements are a big share of our React work. Common patterns: migrating from class components to hooks, untangling Redux into Zustand + React Query, introducing TypeScript across an existing JS codebase, replacing a homegrown component library with a tokens-driven Tailwind + Radix system, and bringing test coverage up to a level the team trusts. We work incrementally so the product keeps shipping during the refactor.
Hooks exclusively. Functional components with hooks, custom hooks for shared logic, suspense boundaries where streaming earns its keep, and React Server Components where the data-loading shape benefits. We don't ship class components in new code, and we'll usually migrate them out during a refactor unless there's a specific lifecycle reason to keep one (extremely rare in 2026).
Unit and integration tests with Vitest, component tests with Testing Library, end-to-end tests with Playwright. Coverage targets are set based on the criticality of each surface — payment flows and core user paths get heavy coverage, marketing surfaces and rarely-used admin screens get less. We don't chase a coverage percentage; we chase confidence that the things that matter are tested.
Yes — this is one of the highest-leverage things we do. We ship a tokens-driven Tailwind config, a Radix-based component library, Storybook with usage examples, and a Figma-to-code pipeline so designers and engineers stay in sync. The result is a system the in-house team continues to extend after we hand off, not a snapshot they're afraid to touch.
Accessibility is a default, not a phase. Components built on Radix primitives are accessible by construction, every PR runs axe-core lint, color-contrast tokens are defined in the design system, and we include a manual screen-reader pass on critical flows before launch. We aim for WCAG 2.2 AA across customer-facing surfaces and target AAA on a case-by-case basis where regulation requires it.
Yes — most React engagements connect to a backend the client already owns. We work over REST, GraphQL, tRPC, gRPC-web, or WebSockets, and we'll tell you honestly when the API shape is causing pain on the frontend so the backend team can decide what to do about it. We don't insist on rewriting your backend; we work with what's there.
A focused feature build runs 4-6 weeks. A full frontend rewrite or design system land takes 8-12 weeks. A long-running embedded engagement on a complex product is sized weekly via a retainer. We commit to dates during scoping, demo weekly, and ship to the schedule we agreed in week one.
Most commonly: Next.js for full-stack, Laravel or Node.js (Hono / NestJS) for the API, PostgreSQL for the database, Vercel or AWS for deployment, and Tailwind plus Radix for UI. We also work with team-specific stacks — Django, Rails, FastAPI — when that's what the backend already is. The React side is stack-agnostic; we work with what's already there.
