React Development Agency
Senior React developers for your next project. React, Next.js, React Native. US timezone.
React powers some of the world's most sophisticated web applications. Getting real value out of it, though, depends on decisions that happen before the first component is written — component architecture, state boundaries, data fetching, rendering strategy, and testing. Those decisions are what separate an application that stays pleasant to extend in year three from one that everybody is quietly afraid to touch by month eight. Our nearshore development team has been making them since 2020.
Codebrand is a React development agency based in San Pedro Sula, Honduras, working in US Central Time. Our engineers write TypeScript by default, review every pull request, and ship to a live preview environment weekly. We build new products, and we take over existing ones — including the ones that arrive with a slow bundle, a half-finished migration, and no tests. If you need the surrounding system too, our custom software development practice covers the APIs, databases, and integrations behind the interface.
You can engage us for a full build, for a dedicated development team that works only on your roadmap, or to hire remote developers who slot into the team you already have. Rates are published and hourly — Mid $45, Senior $65, Lead or Architect $95 — and you own one hundred percent of the code from the first commit. What those rates mean over a real engagement is easier to judge in our nearshore cost calculator, which totals them against a US in-house salary once burden and overhead are included.
One thing worth saying early: React is not always the right answer. A marketing site does not need a component framework shipping hundreds of kilobytes of JavaScript, and we will say so. We also build with Astro and offer straightforward web development when that is the honest fit. There is a section further down explaining exactly where we draw that line.

What we build
React is one word covering five very different kinds of build. The architecture, the testing depth, and the cost of each are not comparable, so here is what we actually deliver and what changes between them. Selling online sits slightly apart and has its own page — see e-commerce development.
Product interfaces where the whole experience lives in the browser — filters, drag-and-drop, optimistic updates, real-time state. We structure them around a real routing layer, server-state caching with TanStack Query, and component boundaries that survive a year of feature requests instead of collapsing into one thousand-line page component.
Operations screens, admin panels, and analytics views that render heavy tables and charts without freezing the tab. This is where virtualization, memoization, and careful data shaping matter most. We have built these for logistics, accounting, and sales teams, and the constraint is always the same: a person uses this eight hours a day, so it has to be fast and quiet.
Multi-tenant products with authentication, role-based permissions, subscription billing, usage limits, and an admin backend. Usually built on Next.js so marketing pages, the app shell, and API routes live in one deployable codebase. We wire in Stripe or PayPal, transactional email, and the audit trails your first enterprise customer will ask about.
Logged-in areas bolted onto an existing business: order history, document access, support tickets, quotes, invoices. These almost always mean integrating with systems that were not designed to be integrated with — an ERP, a legacy SQL database, a SOAP endpoint. We build the adapter layer as carefully as the interface.
One codebase, iOS and Android, sharing types and business logic with your web application. Push notifications, offline caching, camera and location access, app store submission. When a feature genuinely needs native code we write the native module rather than pretending the limitation does not exist.
How we work
These are not aspirations we bring out for sales calls. They are the defaults on every engagement, and they are the reason our handovers do not come with an apology attached.
Every project is TypeScript from the first commit, with strict mode on. Props, API responses, and shared domain models are typed end to end, so a backend field rename becomes a compile error instead of a production incident. We do not scatter any types to make the build pass.
Component and unit tests with Jest and React Testing Library, end-to-end coverage of revenue-critical paths with Playwright or Cypress. We test what a user can observe, not internal implementation, so the suite still passes after a refactor. Everything runs in CI on every pull request.
No code reaches your main branch without a second engineer reading it. Reviews check architecture and readability, not just correctness — naming, component boundaries, dependency choices, accessibility. Small pull requests, reviewed within the working day, so nothing sits in a queue for a week.
We set a JavaScript budget per route at the start and enforce it. Bundles get analyzed, heavy dependencies get questioned, and routes get code-split. Public pages are held to Core Web Vitals thresholds; our own site scores 100/100 on Lighthouse mobile, and we hold client work to the same standard.
Semantic HTML first, ARIA only where it is genuinely needed. Keyboard navigation, focus management in modals and menus, visible focus states, and contrast that passes WCAG AA. Accessible components are also the ones that behave predictably for everyone else.
Server state goes in TanStack Query. Client state goes in local state, context, or Zustand depending on how far it travels. We do not install Redux reflexively — most applications that reach for a global store actually have a data-fetching problem wearing a costume.
Choosing honestly
Agencies that only sell React will tell you every project needs React. We build in three stacks, so we have no reason to push you toward the expensive one. Here is the decision we would make in your seat.
Choose React when users spend real time inside the application: dashboards, editors, booking flows, anything with heavy interactive state, live updates, or complex forms that talk to each other. The component model and the ecosystem around it pay for their weight when the interface is genuinely the product. React is also the right call when you plan to share logic with a React Native mobile app later.
If the same product needs public marketing pages, a blog, and a logged-in app, use Next.js. Server rendering and static generation mean crawlers and users get real HTML instead of an empty shell, and route handlers let the API live beside the interface. This is our default for anything customer-facing and it is where most of our React work lands.
For marketing sites, documentation, blogs, and brochure-style storefronts, an Astro build ships almost no JavaScript and loads faster than a React equivalent can, with interactive React components dropped in only where they are needed. Recommending Astro on a project like that costs us billable hours and saves you money — which is exactly why you should trust the recommendation. We wrote the full comparison, with benchmarks and use cases, in React vs Next.js vs Astro, and one of our own builds shows what the hybrid looks like in practice: interactive components hydrating on demand, 100/100 mobile performance, a 0.9-second LCP and 10 ms of blocking time.
Existing codebases
Slow React applications are slow for a small number of repeat reasons, and guessing at them wastes weeks. We profile first — React DevTools for render behaviour, Lighthouse and real user metrics for delivery — then fix in order of impact. The usual suspects: bundles nobody has analyzed since launch, context providers re-rendering entire trees, request waterfalls where parallel fetches belonged, lists rendering thousands of rows without virtualization, and images shipped at four times their display size. We documented one of these end to end in our React performance case study.
A fixed-scope, read-only review of your codebase, usually a week. We report on architecture and component boundaries, state management, dependency and security health, test coverage, build and CI setup, accessibility, and the specific areas where change is risky. You get a prioritized list with effort estimates that you own outright and can hand to any team — us, your in-house engineers, or another vendor. Most audits end with a plan to fix rather than a plan to rewrite, because full rewrites fail far more often than teams expect.
jQuery, AngularJS, WordPress themes, Create React App, or a Pages Router application that has outgrown its structure. We migrate incrementally, route by route or screen by screen, so your product stays shippable the entire time and your team keeps releasing. Analytics, SEO redirects, and authentication are carried across deliberately, not rediscovered after launch. Big-bang rewrites are where roadmaps go to die, and we have inherited enough of them to avoid starting one.
Sometimes the code is fine and the roadmap is just longer than the team. Our engineers join your repository, your stand-ups, and your review process, follow your conventions rather than importing ours, and take tickets like any other team member. Ramp-up is typically a few days rather than weeks because they have seen most React codebases before.
Engagement
No packages, no mandatory retainers, no fixed-bid theatre that punishes you for changing your mind. You buy engineering hours at a published rate and decide each sprint how many you want.
Transparent tiers with no retainer: Mid-level $45/hour, Senior $65/hour, Lead or Architect $95/hour. You approve an hourly cap per sprint and see a detailed log of where the hours went. Best for defined projects, feature work, and audits.
One or more engineers assigned to you full-time, in your stand-ups and your tracker, working only on your roadmap. Best when the work is continuous and you want the context to accumulate instead of resetting. Scale the team between sprints as priorities change.
One-week sprints. Monday planning against your priorities, a deployed preview environment updated continuously, a Friday demo of working software, and a written summary of what shipped, what is next, and what is blocked. No surprise invoices and no month-long silences.
Every engagement runs through our own production CRM, so time logs, deliverables, and invoices come from the same place rather than three disconnected spreadsheets. If you would rather have engineers reporting directly to your own manager, the dedicated team model is built for exactly that. Work outside React is quoted the same way through our custom web development services.
Timeline
Below is the shape of a mid-sized React application — roughly a ten-week build. Larger products repeat the middle phase; audits and feature work compress it. What does not change is that you see deployed software every week.
We map the product, agree on scope for version one, and choose the stack — rendering strategy, data layer, auth, hosting. You get a written architecture note and an hour estimate before anyone writes feature code.
Repository, CI, typed API client, authentication, routing, and the base component library. By the end of week two there is a deployed environment you can click through, even if it is mostly scaffolding.
The core screens get built, reviewed, tested, and shipped to preview every week. You use the product as it grows and re-prioritize the backlog each Monday based on what you actually see.
Bundle analysis, render profiling, image and font optimization, end-to-end test coverage on critical paths, accessibility pass, and error monitoring wired up before real users arrive.
Production deploy on your infrastructure, environment and secrets documented, a README a new engineer can follow, and a walkthrough recording. You own the repository and every credential.
