React.js development

Interfaces that feel instant, code that stays clean.

React's component model lets teams build rich, interactive interfaces from small, reusable pieces. With Next.js on top, you also get server-side rendering and static generation, which means fast first loads and pages that search engines can read easily.

Our React developers write TypeScript, build a shared component library with Storybook, manage data with React Query or Redux Toolkit, and test with Playwright. Whether you need a new SaaS front end or want to modernise an old jQuery or Angular app, we keep performance and accessibility front and centre.

Client testimonials

What our clients say about us.

"What impressed us most about UD3 Logic was their ability to understand the healthcare industry rather than treating the project like a standard software development assignment. They invested time in learning how our hospital operates, the challenges faced by our staff, and the expectations of our patients before proposing solutions. This resulted in a platform that felt practical and intuitive instead of being overloaded with unnecessary features.

Another standout quality was their willingness to collaborate. They welcomed feedback throughout the project, refined features based on our evolving requirements, and consistently focused on finding the best long-term solution instead of the quickest fix. Their technical expertise, combined with clear communication and genuine commitment to our success, made the entire engagement feel like a true partnership.

Even after the primary development work was completed, they continued to provide valuable support and enhancements, which gave us confidence that the solution would continue to evolve alongside our organization."

Ask a question
WhatsApp +91 98874 87026
Q1Why use React.js for my web application?

React is fast, flexible and widely used, with a huge ecosystem and talent pool. Its component model makes complex interfaces easier to build and maintain, and it pairs well with React Native if you also need mobile apps.

Q2What is the difference between React and Next.js?

React is a library for building user interfaces. Next.js is a framework built on React that adds routing, server-side rendering, static generation and API routes. For public websites and SEO, Next.js is usually the better choice; for internal tools, a plain React SPA can be enough.

Q3Are React websites good for SEO?

Yes, when built with server-side rendering or static generation, as Next.js does. Search engines receive fully rendered HTML, and we add metadata, structured data and fast loading for strong SEO.

Q4Can you migrate our old application to React?

Yes. We often migrate gradually, replacing one section at a time, so users always have a working application and risk stays low.

Q5Do you write tests for React applications?

Yes. We write unit and component tests with Jest and React Testing Library, and end-to-end tests with Playwright for key user journeys.

Q6Can I hire a dedicated React developer?

Yes. You can hire one or more React developers to work full-time on your product, joining your stand-ups and tools, with support from our senior engineers.

Q7Do you also build the back end?

Yes. We build back ends in Node.js, Laravel or Python, or integrate with your existing APIs and headless CMS.

Q8How long does a React project take?

A Next.js marketing site usually takes 3โ€“6 weeks, an MVP web app 8โ€“12 weeks, and larger SaaS front ends 3 months or more.

Q9Can you add AI chat or streaming features to a React app?

Yes. We build chat interfaces, streaming responses and AI-assisted forms in React, connected to secure back-end services that call the AI models.

Q10Can you build a component library for our team?

Yes. We build documented, accessible React component libraries with Storybook and publish them as packages your teams can use.

Q11Can you make my React app faster?

Yes. We profile rendering, reduce bundle size, add code splitting and caching, and fix unnecessary re-renders.

Q12Can you work with our existing designers and back-end team?

Yes. We work from your Figma files and API specifications, and join your stand-ups and code reviews.
