Your React App Ships in Weeks, Not Quarters -- We Build Production Apps Teams Trust

If you're a technical founder watching your roadmap slip another sprint, you need engineers who've shipped 200+ React production deploys -- not contractors learning on your dime.

What Actually Ships When You Hire a React Agency -- And What Breaks Six Months Later

Your React app goes live, traffic hits, and one of two things happens: it holds steady at 90+ Lighthouse under load, or it stalls at 2.4s Time to Interactive and your bounce rate climbs into the 60% range. A React.js development agency builds the first kind -- component architectures on React 19 Server Components, Next.js 15 App Router with edge SSR, TypeScript across every file, and Playwright coverage that blocks merges below 90%. Your team gets a fixed-scope SOW, weekly staging deploys, and a production handoff with monitoring, error tracking, and runbook docs. The difference between us and an offshore quote is what survives past the demo: your app handles real traffic, passes accessibility audits, and doesn't collapse when your product team ships an update nine months later. We staff senior engineers -- minimum five years shipping React in production -- and assign a dedicated tech lead to your engagement. That's what your business actually needs from a React shop.

Your Current Site May Be a Liability

Common gaps we find in nearly every audit.

Your current app scores below 50 on Lighthouse and users bounce before the page finishes loading.
Risk: Every 100ms of load time costs roughly 1% in conversion -- a slow React app is bleeding revenue daily.
The offshore team delivered a working demo, but the codebase has no tests, no types, and no documentation.
Risk: Your next hire will spend 3–6 months untangling spaghetti before they ship a single feature.
You're stuck on Create React App or an old Next.js version and can't adopt Server Components or the App Router.
Risk: Technical debt compounds -- migration costs double roughly every 12 months you wait.
Designers hand off Figma files and what comes back looks nothing like the spec on mobile.
Risk: Rework cycles eat 20–40% of your sprint velocity when there's no design-to-code review loop.
You don't have a CI/CD pipeline, so every deploy is a manual, nerve-wracking push to production.
Risk: One bad merge on a Friday afternoon takes down your app and you don't find out until Monday.
Your React app works but your engineering team can't explain why it's slow or how to fix it.
Risk: Without profiling and bundle analysis, you're guessing -- and guessing doesn't survive a traffic spike.

What We Build

Purpose-built features for your industry.

Lighthouse score under 50 and your page takes 3+ seconds to render -- users are bouncing before they see your product

React 19 Server Components cut your JavaScript bundle in half and render faster on every device your buyers use

Offshore team delivered a working demo but left behind untested, untyped spaghetti that no engineer wants to touch

Next.js 15 App Router with parallel routes and streaming SSR deployed to Vercel edge for sub-200ms TTFB globally

Stuck on Create React App or Next.js 12 and can't adopt Server Components without a full rewrite

Vite builds for standalone SPAs that don't need SSR -- instant HMR in dev, production bundles under 150KB gzipped

Figma handoffs look perfect in the design file but ship broken on mobile because there's no review loop

TypeScript end-to-end, Vitest unit coverage, Playwright E2E suite, CI that blocks any merge dropping below your threshold

No CI/CD pipeline so every deploy is a manual push and one bad Friday merge takes down production until Monday

Supabase auth and Postgres with row-level security, OAuth flows, magic links, real-time subscriptions wired into your components

Your React app works but nobody on your team can profile why it's slow or fix it when traffic spikes

Lighthouse budgets enforced in CI, Core Web Vitals tracked in Vercel Analytics, Sentry error monitoring from day one

Our Development Process

From discovery to launch. Quality at every step.

01

Scope and Architecture Review

Week 1

We audit your existing codebase or requirements, define the component architecture, and deliver a fixed-scope SOW with line-item estimates.

02

Design System + Data Layer

Week 2–3

We build your component library in Storybook, wire up Supabase schemas, and establish the TypeScript interfaces that every feature builds on.

03

Feature Sprints

Week 3–6

Two-week sprints with staging deploys every Friday -- you review working software in a real browser, not a slide deck.

04

Performance + QA Pass

Week 6–7

Lighthouse audits, bundle analysis, Playwright E2E runs, accessibility checks against WCAG 2.2 AA, and load testing up to your target concurrency.

05

Production Deploy + Handoff

Week 7–8

We deploy to Vercel with preview environments, configure monitoring and alerting, and hand over documentation, runbooks, and a 30-day support window.

Frequently Asked Questions

Most engagements fall between $25K and $180K. A scoped MVP with auth, a few CRUD flows, and deployment typically runs $25K–$50K over 4–6 weeks. A full product build with real-time features, admin dashboards, and third-party integrations lands in the $80K–$180K range across 8–14 weeks. We price on fixed-scope SOWs — you'll know the number before we write a line of code. No hourly billing surprises.
Four to eight weeks for most projects. Week one is architecture and scoping. Weeks two through six are feature sprints with weekly staging deploys. Weeks six through eight cover QA, performance tuning, and production handoff. Larger builds with complex integrations can extend to 12–14 weeks, but we'll flag that in the SOW upfront.
React owns roughly 40% of production web apps — your next hire already knows it. React 19 adds Server Components and Actions, which means less client-side JavaScript and faster page loads without ditching the ecosystem. Next.js 15's App Router gives us streaming SSR, edge rendering on Vercel, and file-based routing that keeps codebases navigable at scale. We've evaluated Svelte, Solid, and Astro — they're great for specific use cases — but for teams that need to hire, maintain, and iterate over 3–5 years, React and Next.js are the pragmatic choice.
Two to four engineers plus a dedicated tech lead. The tech lead runs architecture decisions, code reviews, and your weekly sync. Engineers are senior — minimum five years of React production work. We don't backfill with juniors or rotate people mid-sprint. You'll know every name on the team before kickoff.
Yes. We commit to 90+ on Lighthouse performance, accessibility, best practices, and SEO — measured on the production build, on mobile, over a throttled 4G connection. We bake performance budgets into CI so scores can't regress after handoff. If we don't hit 90+ at launch, we fix it at no additional cost.
Every engagement includes a 30-day support window post-launch for bug fixes and configuration issues. Beyond that, we offer monthly retainers starting at $5K for ongoing feature work, performance monitoring, and dependency updates. We also hand over full documentation — architecture diagrams, component docs in Storybook, CI/CD runbooks, and environment setup guides — so your internal team can take over cleanly if you prefer.
Absolutely. About 40% of our engagements start with an existing codebase. We'll run a technical audit in week one — bundle size, test coverage, TypeScript adoption, dependency health, and performance profiling. You'll get a written report with prioritized recommendations and a migration path if you're on an older React or Next.js version. We've migrated apps from CRA to Vite, Pages Router to App Router, and JavaScript to TypeScript more times than we can count.
An offshore team at $30–$50/hr looks cheaper on paper. In practice, we see clients come to us after spending $40K–$80K on offshore builds that lack tests, ship with 300KB+ JavaScript bundles, and break on the first real QA pass. Our fixed-scope pricing means you know the total cost upfront. Our engineers have shipped thousands of React apps on Vercel and Supabase — they won't spend your budget learning the stack. You'll get weekly staging deploys, sub-200ms TTFB, and a codebase your next hire can actually read.
