How long does it take to build a React.js application?

Most MVPs are delivered in 8 to 12 weeks. For example, a custom dashboard with multiple integrations can ship in 10 weeks. IRPR has completed over 200 projects within this timeframe.

What tech stack do you use with React.js?

We primarily use React.js with TypeScript, Next.js for server-side rendering, and state management libraries like Redux or Zustand. For styling, we use Tailwind CSS or Styled Components. The backend often uses Node.js or Python.

Can you integrate React.js with Stripe, Salesforce, or other APIs?

Yes. IRPR has integrated React.js with Stripe for payments, Salesforce for CRM, Twilio for communications, and many other APIs. We handle OAuth, webhooks, and custom data syncs.

Do you build React.js applications for healthcare or fintech?

Yes. We build HIPAA-compliant patient portals and PCI-DSS compliant financial dashboards. IRPR follows security best practices including data encryption and access controls.

Who owns the code after the project?

You own all the source code. IRPR places it in your private repository and transfers all rights. We do not reuse code without permission.

How quickly can we start a project?

We can kick off within 1 to 2 weeks. After a discovery call, we start the Roadmap phase to define scope and price. Most teams begin coding in the third week.

Do you provide ongoing support after launch?

Yes. We include 30 days of post-launch support with Sentry monitoring and bug fixes. Longer-term maintenance agreements are available after the initial period.

Generic agency vs. expert react.js development firm

Not all React.js teams are equal.

Generic agencies often deliver bloated code and miss deadlines.

IRPR writes clean, testable React code with full CI/CD and documentation.

Roadmap

Product

Our engineers build the MVP in 8-12 weeks. We use feature branches, code reviews, and continuous deployment.

Release
