React development services

If you're building a dashboard that handles live data, a portal where users manage complex workflows, or an application where the frontend defines your product, React delivers.

React fits when your application is interactive and data-driven: dashboards, portals, single-page applications, progressive web apps, and frontends over APIs. It's the most widely adopted frontend library in the world, which means a huge ecosystem, long-term viability, and no vendor lock-in. If your project is a content site where a CMS would serve you better, we'll say so.

We work across industries, but the types of applications we build share common threads: they're interactive, they handle complex state, and the interface is central to the product's value.

Client portals and user dashboards

Interfaces where users log in to manage accounts, view data, configure settings, or track activity. AI can add natural-language search, summarize account activity, or guide users through multi-step workflows while respecting each user’s data access and permissions.

Enterprise applications and admin panels

Internal tools where your team manages inventory, processes orders, analyzes performance, or coordinates operations. AI can flag anomalies, forecast demand, or let staff query operational data in plain English, with React presenting the results beside the controls used to act on them.

Ecommerce frontends with custom functionality

Product configurators, personalized shopping experiences, real-time inventory displays, or complex filtering and search. AI can support semantic search, personalized recommendations, and product comparisons, while controlled integrations can make commerce functions available to authorized AI agents.

Single-page applications (SPAs)

Complete applications that load once and dynamically update content as users navigate.

Progressive web apps (PWAs)

Browser-based applications that work offline, sync data in the background, and send push notifications.

Component libraries and design systems

When you need consistency across multiple products or teams, we build reusable React component libraries. These can include shared patterns for AI interactions, such as prompt inputs, streamed responses, source references, approval steps, and clear loading and error states.

Start with Co-Dev when you want to work hands-on on a prototype with us before committing to the production build. Co-Dev uses agentic development to turn your meetings, rough specs, and initial decisions into a functioning prototype where you can make changes yourself. We shape the prototype together: you with the domain knowledge, and 1902 Software with the technical expertise.

Co-Dev can be a good fit when you want to shape:

• A new custom React application with workflows that need to be tested in practice
• A new feature for an existing system, using your current design system where appropriate
• A client portal or dashboard whose behavior is difficult to define in static designs
• An AI-enabled interface or automation that must connect to existing systems

It usually takes one to two weeks to move from intake to a working prototype. The prototype’s fixed price includes a workshop of two sessions before collaborative shaping begins. Once shaping starts, meetings, agentic development guidance, and requested prototype changes are billed at $80 an hour.

The prototype makes workflows, interface behavior, and requirements concrete, but it is not the finished product. You shape it with us using your own AI key and development environment, and we use the settled prototype to scope the production build.

Already have a vibe-coded proof of concept? Through Go-Live, we begin with a paid assessment, determine what can be kept and what must change, and then scope the production build at a fixed price.

A Fixed Price Project turns a Co-Dev prototype or a well-defined brief into a production React application. You get one agreed scope and one price for the whole project, fixed before work begins.

Typical projects include:

• New React applications
• Client portals
• Dashboards
• Single-page applications
• Progressive web apps
• Frontend modernization projects
• Component libraries and design systems

Large projects typically start with Project Scoping at an agreed, prepaid fixed price. This phase defines precisely what will be built and establishes the final price, giving both sides clarity before development begins.

After deployment, ongoing maintenance and improvements can move into Care. A major update can still be scoped as a separate Fixed Price Project when it does not fit ordinary monthly work.

Continuous Monthly Development is the ongoing option for a React application that is already live, whether we built it or are taking it over. Send tasks whenever they arise, from bug fixes and interface changes to integrations and new features.

Care runs entirely in writing at one fixed monthly price, with no estimates to approve and no cost overruns.

Care Plus gives you everything in Care at its own fixed monthly price, plus up to two hours of meetings per month with a Project Manager or any 1902 Software expert, up to two ongoing tasks at a time, and up to two developers working on your tasks at the same time.

Care Ultimate suits ongoing engagements, often across multiple systems, that need closer collaboration. Each task or group of tasks has a fixed price that you approve before work begins. We add people with the right expertise as your needs grow, and meetings with any 1902 Software expert are billed at $80 an hour for the actual time spent.

Typical work includes:

• Bug fixes
• New functionality
• UI and UX improvements
• Performance optimization
• Component refactoring
• API integrations
• Dashboard improvements
• Frontend modernization
• AI implementation
• Ongoing technical support

You can start with Care for an existing application without first using Co-Dev or a Fixed Price Project. The right entry point depends on whether you need to shape, build, or continuously improve the software.

Many of our React clients originally worked with another software development company.

We regularly take over existing React applications, review the existing implementation and continue development with minimal disruption to your business.

React frontends rarely live alone. We connect them to what you already run, .NET and PHP backends, REST and GraphQL APIs, ecommerce platforms, CMSs, and custom systems, so the new frontend works with your existing investment instead of replacing it.

React 18+ with TypeScript, Next.js where server-side rendering or SEO matters, Redux or React Query for state and data, Tailwind or styled-components for styling, and Vitest/Playwright for testing, plus whatever your existing stack requires. We choose per project, not by habit.

Our developers, designers, testers, and project managers use modern AI-assisted tools for planning, design, development, and testing. This results in higher quality and faster delivery. Every solution is still thoroughly reviewed, tested, and verified by experienced software developers and testers.

Beyond using AI to accelerate development, we can build AI-driven functionality directly into your interfaces:

Intelligent search with natural language

Search that understands user intent, handles typos, learns from behavior patterns, and surfaces relevant results instantly, powered by AI that improves over time.

Real-time personalization engines

Interfaces that adapt content, recommendations, and layout based on user behavior, preferences, and historical patterns.

Predictive analytics and forecasting

Dashboards that don't just display data, they predict trends, flag anomalies, identify risks, and help users make proactive decisions based on AI-analyzed patterns.

Natural language interfaces

Let users interact with complex applications using plain English instead of navigating forms and filters. AI parses intent and translates it into actions or queries.

Smart form assistance

Forms that validate intelligently, suggest completions, detect errors before submission, and guide users through complex workflows without frustration.
